Hello Tidy Bot, Alexey Serbin, Kudu Jenkins, Adar Dembo, Greg Solovyev,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#8).
Change subject: KUDU-2069 p1: add persistent tserver maintenance mode

KUDU-2069 p1: add persistent tserver maintenance mode
Adds tablet server states to the master, with which to represent tablet
server maintenance mode (and in the future, decommissioning).
The on-disk state is represented as an entry in the system catalog
table, keyed by the tserver UUID. The in-memory state is maintained by
the TSManager as a mapping from tserver UUID to the new TServerStatePB
enum.
Note that this patch only introduces the states internally and doesn't
expose a way for users to set them.
Testing:
- test to check that maintenance mode is maintained through a restart of
the master
- test to ensure that repeated setting of state does not affect the
in-memory tserver states
- test that concurrently updates tserver state and ensures that the
results in-memory match with what's on-disk
