If a manual failover got timed out, like the election don't get the
enough votes, since we have a auth_timeout and a auth_retry_time, a
new manual failover will not be able to proceed on the replica side.
Like if we initiate a new manual failover after a election timed out,
we will pause the primary, but on the replica side, due to retry_time,
replica does not trigger the new election and the manual failover will
eventually time out.
In this case, if we initiate manual failover again and there is an
ongoing election, we will reset it so that the replica can initiate
a new election at the manual failover's request.
