675c7b7e26 Correct a dial race condition (#2992)
## Issue Addressed

On a network with few nodes, it is possible that the same node can be found from a subnet discovery and a normal peer discovery at the same time.

The network behaviour loads these peers into events and processes them when it has the chance. It can happen that the same peer can enter the event queue more than once and then attempt to be dialed twice. 

This PR shifts the registration of nodes in the peerdb as being dialed before they enter the NetworkBehaviour queue, preventing multiple attempts of the same peer being entered into the queue and avoiding the race condition.

615695776e Retry gossipsub messages when insufficient peers (#2964)
## Issue Addressed
#2947 

## Proposed Changes

Store messages that fail to be published due to insufficient peers for retry later. Messages expire after half an epoch and are retried if gossipsub informs us that an useful peer has connected. Currently running in Atlanta

## Additional Info
If on retry sending the messages fails they will not be tried again

bdd70d7aef Reduce gossip history (#2969)
The gossipsub history was increased to a good portion of a slot from 2.1 seconds in the last release.

Although it shouldn't cause too much issue, it could be related to recieving later messages than usual and interacting with our scoring system penalizing peers. For consistency, this PR reduces the time we gossip messages back to the same values of the previous release.

It also adjusts the gossipsub heartbeat time for testing purposes with a developer flag but this should not effect end users.

ca29b580a2 Increase target subnet peers (#2948)
In the latest release we decreased the target number of subnet peers. 

It appears this could be causing issues in some cases and so reverting it back to the previous number it wise. A larger PR that follows this will address some other related discovery issues and peer management around subnet peer discovery.

fc7a1a7dc7 Allow disconnected states to introduce new peers without warning (#2922)
## Issue Addressed

We emit a warning to verify that all peer connection state information is consistent. A warning is given under one edge case;
We try to dial a peer with peer-id X and multiaddr Y. The peer responds to multiaddr Y with a different peer-id, Z. The dialing to the peer fails, but libp2p injects the failed attempt as peer-id Z. 

In this instance, our PeerDB tries to add a new peer in the disconnected state under a previously unknown peer-id. This is harmless and so this PR permits this behaviour without logging a warning.

ef7351ddfe Update to spec v1.1.8 (#2893)
## Proposed Changes

Change the canonical fork name for the merge to Bellatrix. Keep other merge naming the same to avoid churn.

I've also fixed and enabled the `fork` and `transition` tests for Bellatrix, and the v1.1.7 fork choice tests.

Additionally, the `BellatrixPreset` has been added with tests. It gets served via the `/config/spec` API endpoint along with the other presets.

1c667ad3ca PeerDB Status unknown bug fix (#2907)
## Issue Addressed

The PeerDB was getting out of sync with the number of disconnected peers compared to the actual count. As this value determines how many we store in our cache, over time the cache was depleting and we were removing peers immediately resulting in errors that manifest as unknown peers for some operations.

The error occurs when dialing a peer fails, we were not correctly updating the peerdb counter because the increment to the counter was placed in the wrong order and was therefore not incrementing the count. 

This PR corrects this.

6f4102aab6 Network performance tuning (#2608)
There is a pretty significant tradeoff between bandwidth and speed of gossipsub messages. 

We can reduce our bandwidth usage considerably at the cost of minimally delaying gossipsub messages. The impact of delaying messages has not been analyzed thoroughly yet, however this PR in conjunction with some gossipsub updates show considerable bandwidth reduction. 

This PR allows the user to set a CLI value (`network-load`) which is an integer in the range of 1 of 5 depending on their bandwidth appetite. 1 represents the least bandwidth but slowest message recieving and 5 represents the most bandwidth and fastest received message time. 

For low-bandwidth users it is likely to be more efficient to use a lower value. The default is set to 3, which currently represents a reduced bandwidth usage compared to previous version of this PR. The previous lighthouse versions are equivalent to setting the `network-load` CLI to 4.

This PR is awaiting a few gossipsub updates before we can get it into lighthouse.

aaa5344eab Add peer score adjustment msgs (#2901)
## Issue Addressed

## Proposed Changes

This PR adds the `msg` field to `Peer score adjusted` log messages. These `msg` fields help identify *why* a peer was banned.

Example:

There is also a `libp2p_report_peer_msgs_total` metrics which allows us to see count of reports per `msg` tag.

b22ac95d7f v1.1.6 Fork Choice changes (#2822)
## Issue Addressed

Resolves: https://github.com/sigp/lighthouse/issues/2741
Includes: https://github.com/sigp/lighthouse/pull/2853 so that we can get ssz static tests passing here on v1.1.6. If we want to merge that first, we can make this diff slightly smaller

## Proposed Changes

- Changes the `justified_epoch` and `finalized_epoch` in the `ProtoArrayNode` each to an `Option<Checkpoint>`. The `Option` is necessary only for the migration, so not ideal. But does allow us to add a default logic to `None` on these fields during the database migration.
- Adds a database migration from a legacy fork choice struct to the new one, search for all necessary block roots in fork choice by iterating through blocks in the db.
- updates related to https://github.com/ethereum/consensus-specs/pull/2727
  -  We will have to update the persisted forkchoice to make sure the justified checkpoint stored is correct according to the updated fork choice logic. This boils down to setting the forkchoice store's justified checkpoint to the justified checkpoint of the block that advanced the finalized checkpoint to the current one. 
  - AFAICT there's no migration steps necessary for the update to allow applying attestations from prior blocks, but would appreciate confirmation on that
- I updated the consensus spec tests to v1.1.6 here, but they will fail until we also implement the proposer score boost updates. I confirmed that the previously failing scenario `new_finalized_slot_is_justified_checkpoint_ancestor` will now pass after the boost updates, but haven't confirmed _all_ tests will pass because I just quickly stubbed out the proposer boost test scenario formatting.
- This PR now also includes proposer boosting https://github.com/ethereum/consensus-specs/pull/2730

## Additional Info
I realized checking justified and finalized roots in fork choice makes it more likely that we trigger this bug: https://github.com/ethereum/consensus-specs/pull/2727

It's possible the combination of justified checkpoint and finalized checkpoint in the forkchoice store is different from in any block in fork choice. So when trying to startup our store's justified checkpoint seems invalid to the rest of fork choice (but it should be valid). When this happens we get an `InvalidBestNode` error and fail to start up. So I'm including that bugfix in this branch.

Todo:

- [x] Fix fork choice tests
- [x] Self review
- [x] Add fix for https://github.com/ethereum/consensus-specs/pull/2727
- [x] Rebase onto Kintusgi 
- [x] Fix `num_active_validators` calculation as @michaelsproul pointed out
- [x] Clean up db migrations

6625aa4afe Status'd Peer Not Found (#2761)
## Issue Addressed

Users are experiencing `Status'd peer not found` errors

## Proposed Changes

Although I cannot reproduce this error, this is only one connection state change that is not addressed in the peer manager (that I could see). The error occurs because the number of disconnected peers in the peerdb becomes out of sync with the actual number of disconnected peers. From what I can tell almost all possible connection state changes are handled, except for the case when a disconnected peer changes to be disconnecting. This can potentially happen at the peer connection limit, where a previously connected peer switches to disconnecting. 

This PR decrements the disconnected counter when this event occurs and from what I can tell, covers all possible disconnection state changes in the peer manager.

0b319d4926 Inform dialing via the behaviour (#2814)
I had this change but it seems to have been lost in chaos of network upgrades.

The swarm dialing event seems to miss some cases where we dial via the behaviour. This causes an error to be logged as the peer manager doesn't know about some dialing events. 

This shifts the logic to the behaviour to inform the peer manager.

53562010ec Move peer db writes to eth2 libp2p (#2724)
## Issue Addressed
Part of a bigger effort to make the network globals read only. This moves all writes to the `PeerDB` to the `eth2_libp2p` crate. Limiting writes to the peer manager is a slightly more complicated issue for a next PR, to keep things reviewable.

## Proposed Changes
- Make the peers field in the globals a private field.
- Allow mutable access to the peers field to `eth2_libp2p` for now.
- Add a new network message to update the sync state.

fbafe416d1 Move the peer manager to be a behaviour (#2773)
This simply moves some functions that were "swarm notifications" to a network behaviour implementation.

Notes
------
- We could disconnect from the peer manager but we would lose the rpc shutdown message
- We still notify from the swarm since this is the most reliable way to get some events. Ugly but best for now
- Events need to be pushed with "add event" to wake the waker

df40700ddd Rename eth2_libp2p to lighthouse_network (#2702)
## Description

The `eth2_libp2p` crate was originally named and designed to incorporate a simple libp2p integration into lighthouse. Since its origins the crates purpose has expanded dramatically. It now houses a lot more sophistication that is specific to lighthouse and no longer just a libp2p integration. 

As of this writing it currently houses the following high-level lighthouse-specific logic:
- Lighthouse's implementation of the eth2 RPC protocol and specific encodings/decodings
- Integration and handling of ENRs with respect to libp2p and eth2
- Lighthouse's discovery logic, its integration with discv5 and logic about searching and handling peers. 
- Lighthouse's peer manager - This is a large module handling various aspects of Lighthouse's network, such as peer scoring, handling pings and metadata, connection maintenance and recording, etc.
- Lighthouse's peer database - This is a collection of information stored for each individual peer which is specific to lighthouse. We store connection state, sync state, last seen ips and scores etc. The data stored for each peer is designed for various elements of the lighthouse code base such as syncing and the http api.
- Gossipsub scoring - This stores a collection of gossipsub 1.1 scoring mechanisms that are continuously analyssed and updated based on the ethereum 2 networks and how Lighthouse performs on these networks.
- Lighthouse specific types for managing gossipsub topics, sync status and ENR fields
- Lighthouse's network HTTP API metrics - A collection of metrics for lighthouse network monitoring
- Lighthouse's custom configuration of all networking protocols, RPC, gossipsub, discovery, identify and libp2p. 

Therefore it makes sense to rename the crate to be more akin to its current purposes, simply that it manages the majority of Lighthouse's network stack. This PR renames this crate to `lighthouse_network`
