Leader election defaults were updated

- Leader election now acquires the lock before main begins
- Updated leader election lease duration 15s --> 60s, renewal deadline 10s --> 30s and retry period 2s --> 15s
- Shorter default leader election renewal deadline of 10s causes failure while renewing lease in a network intense cluster
