Paul Hauner 6ea3bc5e52 Implement VC API (#1657) 
## Issue Addressed

NA

## Proposed Changes

- Implements a HTTP API for the validator client.
- Creates EIP-2335 keystores with an empty `description` field, instead of a missing `description` field. Adds option to set name.
- Be more graceful with setups without any validators (yet)
    - Remove an error log when there are no validators.
    - Create the `validator` dir if it doesn't exist.
- Allow building a `ValidatorDir` without a withdrawal keystore (required for the API method where we only post a voting keystore).
- Add optional `description` field to `validator_definitions.yml`

## TODO

- [x] Signature header, as per https://github.com/sigp/lighthouse/issues/1269#issuecomment-649879855
- [x] Return validator descriptions
- [x] Return deposit data
- [x] Respect the mnemonic offset
- [x] Check that mnemonic can derive returned keys
- [x] Be strict about non-localhost
- [x] Allow graceful start without any validators (+ create validator dir)
- [x] Docs final pass
- [x] Swap to EIP-2335 description field. 
- [x] Fix Zerioze TODO in VC api types.
- [x] Zeroize secp256k1 key

## Endpoints

- [x] `GET /lighthouse/version`
- [x] `GET /lighthouse/health`
- [x] `GET /lighthouse/validators` 
- [x] `POST /lighthouse/validators/hd`
- [x] `POST /lighthouse/validators/keystore`
- [x] `PATCH /lighthouse/validators/:validator_pubkey`
- [ ] ~~`POST /lighthouse/validators/:validator_pubkey/exit/:epoch`~~ Future works

Lighthouse: Ethereum 2.0

An open-source Ethereum 2.0 client, written in Rust and maintained by Sigma Prime.

Build Status Book Status Chat Badge

Documentation

Overview

Lighthouse is:

  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing has begun and security reviews are underway.
  • Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
  • Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys and private individuals.
  • Actively involved in the specification and security analysis of the emerging Ethereum 2.0 specification.

Like all Ethereum 2.0 clients, Lighthouse is a work-in-progress.

Development Status

Current development overview:

  • Specification v0.12.3 implemented, optimized and passing test vectors.
  • Rust-native libp2p with Gossipsub and Discv5.
  • RESTful JSON API via HTTP server.
  • Events via WebSocket.
  • Metrics via Prometheus.

Roadmap

  • April 2019: Inital single-client testnets.
  • September 2019: Inter-operability with other Ethereum 2.0 clients.
  • Q1 2020: lighthouse-0.1.0 release: All major phase 0 features implemented.
  • Q2 2020: Public, multi-client testnet with user-facing functionality.
  • Q2 2020: Third-party security review.
  • Q3 2020: Additional third-party security reviews.
  • Q3 2020: Long-lived, multi-client Beacon Chain testnet
  • Q4 2020: Production Beacon Chain (tentative).
