Description

Looking at the code of HMSFollower, we seem to be establishing HMS connection for all servers of Sentry servers irrespective of whether they are leader or not. Whereas the subsequent operations of HMSFollower are only limited to the leader of the Sentry group. To avoid extra connections, we can limit only the leader to get a connection to HMS.
