Enable all cross cluster replication APIs
As an OpenSearch operator
I want to be able to pause, stop, and start cross cluster replication
so that I can use this feature to support failover in a disaster recovery scenario.
Typically in Elasticsearch or Opensearch, CCR can be used to support a DR deployment by placing two clusters (a leader and follower) in separate regions. When the leader cluster becomes unavailable, applications/clients can failover to the follower cluster by stopping replication on the following cluster which makes it a regular index.

shared this idea
Currently we are controlling this process of start/pause etc so we can control replication process during the entire cluster's lifecycle (through all the node recycling, upgrading etc.) to ensure the stability of our services.
I put this to Gather interest, I am also aware of the failover capability mentioned in the ideas as well (we have different ideas ticket for that), this is something we can have a look and see if we need to expose all APIs if the main usecase is failover
