Part of creating support for mixed cluster versions #3881
There has already been a POC for this that can be adopted for this: https://github.com/Poojita-Raj/OpenSearch/commits/rollingUpgrade

Describe the solution you'd like
Default codecs mixed cluster version needs to support:

  1. Loading and using older codec while upgrade is in progress.
  2. Mapping of OS versions to respective codecs.
  3. Upgrading all older codec version segments to newer codecs once nodes are upgraded.
  4. Testing all the upgrade scenarios - [Segment Replication][Rolling upgrade] Create integration tests to simulate rolling upgrade scenarios #7490

Closing out this issue as this implementation of the solution was discarded in favor of adding in a shard_movement_strategy setting as mentioned in #3881
