> As someone who deals with different clusters running different versions (sometimes pre-releases),
I often end up with an error log but not great info as the exact revision the log came from.
This is even more tricky with things like rolling update.
> To help with this, the RS and Master should log their complete version string at startup.
Potentially, they could also log it once every 12 hours as well, so that even with log rotation
we can tell the current version.
