Fix validator lockfiles (#1586)
## Issue Addressed

- Resolves #1313 

## Proposed Changes

Changes the way we start the validator client and beacon node to ensure that we cleanly drop the validator keystores (which therefore ensures we cleanup their lockfiles).

Previously we were holding the validator keystores in a tokio task that was being forcefully killed (i.e., without `Drop`). Now, we hold them in a task that can gracefully handle a shutdown.

Also, switches the `--strict-lockfiles` flag to `--delete-lockfiles`. This means two things:

1. We are now strict on lockfiles by default (before we weren't).
1. There's a simple way for people delete the lockfiles if they experience a crash.

## Additional Info

I've only given the option to ignore *and* delete lockfiles, not just ignore them. I can't see a strong need for ignore-only but could easily add it, if the need arises.

I've flagged this as `api-breaking` since users that have lockfiles lingering around will be required to supply `--delete-lockfiles` next time they run.

Lighthouse: Ethereum 2.0

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

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).
