> During HMSFollower start up, when retrieving HMS full snapshot, also need to
> ensure point-in-time snapshot consistency.
> It should be:
> * Read current HMS notification ID_initial
> * Read HMS metadata state
> * Read current notification ID_new
> * If ID_initial != ID_new then discard the current state and goto 1.
> Use configurable property: sentry.hms.snapshot.retries.max.count for max
> number of retry.
> Ideally, during fetching full snapshot, there should be no write activity on
> the HMS.
