[Remote Store - Dual Replication] Create missing Retention Leases for docrep shard copies during failover

[shourya035]

Description

Recreate Retention Leases after activating primary mode for docrep shard copies. This is useful in dual replication cases where a remote primary fails over to another remote replica, but the replication group still has a docrep replica in it.

We are utilizing the already available createMissingPeerRecoveryRetentionLeases by adding a check to see if the current replication group has at-least one docrep copy. If a retention lease already exists, the method is a NoOp, if it doesn't creates a new one from the current visible global ckp.

Added integ tests around this scenario also

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.x
# Create a new branch
git switch --create backport/backport-13159-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 3c8eafdb7d59647b169e8dd9e5b00e64b82a01e6
# Push it to GitHub
git push --set-upstream origin backport/backport-13159-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-13159-to-2.x.
