Mason Stallmo bc14d1d73d Add more unix signal handlers (#2486)
## Issue Addressed

Resolves #2114 

Swapped out the ctrlc crate for tokio signals to hook register handlers for SIGPIPE and SIGHUP along with SIGTERM and SIGINT.

## Proposed Changes

- Swap out the ctrlc crate for tokio signals for unix signal handing
- Register signals for SIGPIPE and SHIGUP that trigger the same shutdown procedure as SIGTERM and SIGINT

## Additional Info

I tested these changes against the examples in the original issue and noticed some interesting behavior on my machine. When running `lighthouse bn --network pyrmont |& tee -a pyrmont_bn.log` or `lighthouse bn --network pyrmont 2>&1 | tee -a pyrmont_bn.log` none of the above signals are sent to the lighthouse program in a way I was able to observe. 

The only time it seems that the signal gets sent to the lighthouse program is if there is no redirection of stderr to stdout. I'm not as familiar with the details of how unix signals work in linux with a redirect like that so I'm not sure if this is a bug in the program or expected behavior.

Signals are correctly received without the redirection and if the above signals are sent directly to the program with something like `kill`.

The Lighthouse team acknowledges 0x00000000219ab540356cBB839Cbe05303d7705Fa as the canonical Eth2 deposit contract address.

Documentation

The Lighthouse Book contains information for users and developers.

The Lighthouse team maintains a blog at lighthouse.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.

Branches

Lighthouse maintains two permanent branches:

  • stable: Always points to the latest stable release.
    • This is ideal for most users.
  • unstable: Used for development, contains the latest PRs.
    • Developers should base their PRs on this branch.
