Remove http_addresses from Remote Cluster Info API #29207
Description
We currently make node info API requests to remote clusters as part of the Remote Cluster Info API in order to return information about http_addresses of the remote nodes.
http_addresses was originally introduced for kibana to do _field_caps but this is not used in any actionable way and could be removed from the response or replaced with transport addresses, so that the the remote nodes info API calls can be skipped.
Worth noting here that these API calls also require additional privileges for users running x-pack security.
