Cockroach runner for fleet system
- Manages a CA and peers using the fleet system (CA private key is shared for now, since that's the same as using the cryptseed).
- will create node CA and root user certificate
- certificates stored in ~/.config/froach and data in ~/.cache/froach/db
- Able to download latest version of cockroachdb in ~/.cache/froach (will use azusa if found)
It will launch a daemon listening on port 36257 and connect the various daemons together.
