This PR does two things:
- Only run the tests when relevant files change.
- Cache the Go Modules directory between runs, so they don't have to redownload everything everytime (go.sum is the cache key). Pretty much straight from the examples: https://github.com/actions/cache/blob/master/examples.md#go---modules
This script will be triggered by any tag starting with `v[0-9]+.[0-9]+.[0-9]+` (i.e.
v1.1.0). It will create all of the .tar.gz files (or .zip for windows). The amd64 binaries will be
compiled on their target systems, the rest of the Linux architecures
will be cross compiled from the Linux amd64 host.
A SHASUM256.txt will also be generated and attached to the release.
This change adds a new Github Action, a 3 node smoke test. It starts
three docker containers (one lighthouse and two standard nodes) and
tests that they can all ping each other. This should hopefully detect
any basic runtime failures in PRs.
