IMPALA-5043: diagnostics for topic staleness in AC
The default threshold for the admission control topic to be considered
stale is 5s.
Adds diagnostics for stale topic updates:
* A banner on the /admission web UI if the topic is considered stale.
* Time since last update on the /admission web UI
* Append a warning to rejection/queuing messages where topic staleness
may have affected the decision.
* Append a warning to profiles of admitted queries where the topic was
stale at the time the query was admitted.
* Include the topic staleness in all profiles of admitted queries
Testing:
Add a custom cluster test that kills the statestore, validates that
admission control behaves as expected and that stateless warnings
show up in the appropriate places.
