Leader election acquire loop should fail if the cluster is not reachable.

[sarthakkothari]

Problem:

The leader election acquisition loops currently attempts indefinitely to acquire a leader, even if the cluster is unreachable.

Proposed Solution:

We should introduce a configurable timeout to bail out and fail the leader election process if the cluster is not reachable within a specified time. By default, we can retain the current behavior of indefinite retries, but we should allow users to configure this timeout, either to enable the timeout or to adjust its duration.
