[Feature Request] Unset discoveryNodes object from BaseNodeRequest sent over Transport

Is your feature request related to a problem? Please describe

As highlighted in #14749, passing the discovery nodes over transport between nodes for any TransportNodesAction is a costly operation. As part of #15131, initialization of discovery nodes object was made conditional based on the extending action. With this change in opensearch project, discovery nodes information is now not sent over transport for all actions extending TransportNodesAction nodes except for TransportNodesReloadSecureSettingsAction.

With the new major version release we can introduce a breaking change to unset the discovery nodes object in BaseNodesRequest when sending request over transport to individual nodes and any action requiring this information should handle this as part of it's own action request instead of relying on the base request.
