BUG 2371 : Leader should reset it's snapshot tracking when follower is restarted

This patch adds a new protocol to InstallSnapshot. It the InstallSnapshotReply returns
a failure and the chunkIndex is -1 then the Leader will reset the FollowerSnapshot so
that when the next heartbeat occurs the Leader would start sending chunks from the beginning.
