Change subject: Revert "KUDU-1490: Show software version of tablet servers"
......................................................................


Patch Set 1:

This is necessary for _rolling downgrade_ but shouldn't be necessary for a 
"turn everything off and restart with the old version" downgrade, right?

The check only happens if you have a new master running, and you restart a 
tablet server with a different version. I think this would also constrain our 
ability to do rolling uprgade (must upgrade TS before masters)
