Investigate use of health checks adapter in LeaderElection

[ugur99]

LeaderElection has an option to specify a health checks adapter. We may need to consider investigating whether this adapter can be useful.

See: #20

Hey @mneverov - I did some research on the leader elector health checker. It was introduced as a workaround of the following issue - kubernetes/kubernetes#70819
The issue stems from golang.org/x/net/ library that had a deadlock. To mitigate the issue the health checker was introduced so the deadlock could be detected.

However, the real fix of the issue was introduced with golang 1.11 where the deadlock was removed - golang/net@6a8eb5e

Since we are already on the golang 1.20 I don't reason to implement this.
