Assess adding Buildbuddy as a server/remote cache implementation
"BuildBuddy is free for individual developers, small companies, and open source projects."
AFAICT self hosted is non-free (open core), as such our integration could look at hooking into their deployment. However standalone containers could be used https://github.com/buildbuddy-io/buildbuddy/blob/master/docs/on-prem.md without 'enterprise' features.
