[Remote State Repositories] Introduce a new prefix for configuring remote publication repositories

[rajiv-kv]

Is your feature request related to a problem? Please describe

For remote clusters, that store segment and translog in remote, the repositories are configured as node attributes with attribute prefix remote_store. This causes limitation for clusters which want to store only metadata in remote. As the repositories for cluster-state and routing-table also use the same prefix remote_store, it causes cluster-manager to incorrectly assume that publication nodes as remote nodes.

Describe the solution you'd like

We can introduce a new attribute prefix remote_publication to configure publication repositories and make the prefix configurable via static setting. Since the attributes of remote_store and remote_publication configuration don’t overlap, the validation of repository attributes during NodeJoin would be evaluated only for the corresponding node types by cluster-manager.
