Daryn Sharp updated YARN-355:
-----------------------------
Attachment: YARN-355.patch
Things got shuffled on main and caused dependency woes.
Removed private renew/cancel from YarnClientImpl that essentially was commented
as it shouldn't be there. Moved renewer into identifier class like other
tokens. Added much better tests. Otherwise it's pretty much the same as the
original patch.

> The RM performs a loopback connection to itself to renew its own tokens. If
> app submissions consume all RPC handlers for {{ClientRMProtocol}}, then app
> submissions block because it cannot loopback to itself to do the renewal.
