[Remote State] Send remote state location in node join flow

[soosinha]

Is your feature request related to a problem? Please describe

The cluster state publication flow has been modified for remote state to send the remote state location to the follower nodes. The follower nodes download the cluster state directly from remote store rather than getting it from the active cluster manager over transport layer. But in the node join flow, the active cluster manager still sends the full cluster state to the joining nodes.

Describe the solution you'd like

Modify the validate join flow to send the remote cluster state location and then download the cluster state from remote on the follower node
