[master] KUDU-3322 / KUDU-3319 HMS event logging

It would be useful to have additional logging in cases where HMS
notification events have to be analyzed from Kudu side. The Jiras
have more context on the reasoning behind this but this patch adds
* an INFO level log which shows the last processed HMS event id during
startup and
* an ERROR log if the latest event id from HMS is less than
the last seen event id from the master. Was hesitant on crashing the
master and chose to log an ERROR as in the case an out of order event
id received from HMS might lead to unnecessary crash of the Kudu
master.
