Jenkins reported deprecation warnings, but they are in files unchanged by this patch.

I'll plan on committing this to trunk, branch-3.3 and branch-3.2 next week.

[hotcodemacha]

Thanks @cnauroth for reviewing.

LGTM +1

I committed this to trunk and branch-3.3, resolving a minor merge conflict due to differences in the code for TimelineVersionWatcher. I did not commit to branch-3.2, because the classes are still used there by TestDistributedShell.

@ashutoshcipher , thank you for cleaning up unused code. @slfan1989 , thank you for the help with code review.
