Michael Sproul 3486d6a809 Use OS file locks in validator client (#1958) ... ## Issue Addressed Closes #1823 ## Proposed Changes * Use OS-level file locking for validator keystores, eliminating problems with lockfiles lingering after ungraceful shutdowns (`SIGKILL`, power outage). I'm using the `fs2` crate because it's cross-platform (unlike `file-lock`), and it seems to have the most downloads on crates.io. * Deprecate + disable `--delete-lockfiles` CLI param, it's no longer necessary * Delete the `validator_dir::Manager`, as it was mostly dead code and was only used in the `validator list` command, which has been rewritten to read the validator definitions YAML instead. ## Additional Info Tested on: - [x] Linux - [x] macOS - [x] Docker Linux - [x] Docker macOS - [ ] Windows		2020-11-26 11:25:46 +00:00
