Handling NO Coordinator Scenario and Data Loss in the current Design

[kumarpritam863]

This PR combines the issues I have already handled by these two PRs:

1. No Coordinator Scenario in ICR Mode -> Workers gets stuck as there is no-coordinator for emitting Start_Commit request in Incremental Cooperative Rebalancing[ICR] Mode #11288
2. Data Loss in ICR Mode -> Data loss in the Incremental Co-operative Mode of Rebalancing #11289

With this PR, I have made few changes to handle both the issues in more robust, resilient and performant ways.
I have another design change proposal with this PR which handles much more scenarios without doing any OffsetSync or other efforts in much more resilient ways.

The explanantion and the pictorial view of the issues ca be found in this Design change proposal doc which is proposing the changes made by this PR

@bryanck Sir, can we please review this. This PR handles the most of the ICR issues in the current design itself with slight modifications. We can discuss more on this PR which proposes more robust and resilient and connect friendly design.
