[SENTRY-2114] Fix behavior of HMSFollower when HDFS sync is not enabled

• Type: Bug

Description

Currently behavior of HMSFollower when HDFS sync disabled is as below.

1. Take full snapshot of HMS
2. Take the Notification Id from the snapshot created.
3. Persist the notification Id to SENTRY_HMS_NOTIFICATION_ID table
4. Fetches notifications and process new notifications after that point.

This doesn't make sense. Ideally, I think it should work as below.

1. Initially, fetch all the notifications with even-id > 0 and process them.
2. Subsequently fetch and process new notifications.
