This is aproposal for an additional flag --manual-stateless-deal and a
corresponding API endpoint ClientStatelessDeal. This allows firing off
an offline-style deal against a miner without keeping further track of
it locally.
Not keeping any local state introduces the limitation of requiring free
storage deals, as there is nothing to tie the payment channel setup to.
Rationale/need for this type of flow is the case of incredibly large
sets of data nd deals, where the client and providers have prearranged
payment ahead of time, and the client has a separate-from-lotus database
of deal inventory. This way the client can use their lotus node merely
as a network gateway, without running into any limitations currently
present in both lotus as a whole and go-fil-markets in particular.
Specific context for this work is filecoin-discover, where the requirement
is to onboard ~ 12,000,000 individual deals against a pool of miners
with whom the client has prearranged a relationship.

Removing method example pairings since they were

Improved schema examples by using the ExampleValue
method instead of the map lookup.
Made a note in the comment here that this is
not ideal, since we have to make a shortcut assumption
/workaround by using 'unknown' as the method name
and the typea as its own parent.
Luckily these values aren't heavily used by the
method logic.

This paves the way for better object lifetime management.
Concretely, it makes it possible to:
- have different stores backing chain and state data.
- having the same datastore library, but using different parameters.
- attach different caching layers/policies to each class of data, e.g.
sizing caches differently.
- specifying different retention policies for chain and state data.
This separation is important because:
- access patterns/frequency of chain and state data are different.
- state is derivable from chain, so one could never expunge the chain
store, and only retain state objects reachable from the last finality
in the state store.
The bug is applying all messages from given From address are priors
before appling the message that we are estimating.
If user tries replacing message in the middle with gas limit estimation
then message sequence is off and user will either get an execution error
or gas mis-esimation.

This pulls in the improvements introduced in:
- https://github.com/raulk/go-watchdog/releases/tag/v1.0.0
- https://github.com/raulk/go-watchdog/releases/tag/v1.0.1
Lotus tries to initialize the watchdog in the following order of precedence:
1. If a max heap limit has been provided, initialize a heap-driven watchdog.
2. Else, try to initialize a cgroup-driven watchdog.
3. Else, try to initialize a system-driven watchdog.
4. Else, log a warning that the system is flying solo, and return.
This PR also enabled automatic heap profile capture when memory usage
surpasses 90% of the limit. Profiles are written to <LOTUS_HOME>/heapprof.
A single heap profile is captured per episode, with a max of 10 episodes
captured during the lifetime of the process. Episode = instance of usage
climbing above the 90% threshold.
The aim is to put some negative pressure on gas-premium instead of
maintining status quo.
55th percentile instead of median should not make much difference for
block inclusion timing.

_Always_ (almost) use the tipset's parent state, instead of computing.
Exceptions:
* MinerGetBaseInfo. Fixing this would break things so we need to be
careful (although we could bump the API version, fix it, then fix the call
sites).
* StateReplay. This is replaying a message on top of the given tipset.
* GasEstimateGasLimit. This executes the message on-top-of the tipset's
computed state (unlike call which executes it on the tipset's parent state).
* Having this method and Call apply the message at different heights is really
weird.
Instead, use proof type from miner actor. This will, in turn, use the upgraded
proof type if/when it's switched at runtime.
TODO: Consider making this some form of config option instead?
This is terrible, but we don't (currently) update this in the miner info.
Q: Maybe we should delay this by a few epochs? Some pre-commits could fail if we
get a reorg.
Some components like go-ds-measure, go-ipfs-blockstore and go-bitswap
expose metrics via ipfs/go-metrics-interface, but Lotus never injects
the Prometheus exporter (ipfs/go-metrics-prometheus). Therefore, those
metrics never surface in instrumentation.
Instead, Lotus uses OpenCensus directly.
This commit injects the Prometheus exporter for go-metrics-interface, and
instructs the OpenCensus Prometheus exporter to use the DefaultRegistry.
This has the effect of exposing blending the metrics of both metrics
libraries.
With this patch, the datastore, cache utilisation, and bitswap metrics
are now exported via the /debug/metrics endpoint.
This commit also fixes an issue where the metrics scope was empty, making
go-metrics-interface default to "<no-scope>". Angle brackets are inadmissible
characters for Prometheus, so it was refusing to export the affected metrics.
(These were the ARC cache metrics.)
