> 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.
