What do you want to do?

• Request a change to existing documentation
• Add new documentation
• Report a technical problem with the documentation
• Other

Tell us about your request. Provide a summary of the request and all versions that are affected.

1. Add new setting cluster.index.restrict.replication.type that prevents overriding replication type setting at index level.
2. cluster.indices.replication.strategy setting today allows user to enable replication type setting at cluster level. Setting this at cluster level imposes replication type settings on certain actions which create new indices such as split, clone, index templates etc, need to call out in existing documentation.

What other resources are available? Provide links to related issues, POCs, steps for testing, etc.
