[RW Separation] Change search replica recovery flow

[mch2]

Search replicas are currently configured to recover with the Peer recovery flow. To ensure these shards have reduced (node-node replication) and zero (remote backed) communication with primary shards during recovery we need to change this.

In both cases, I think we can initialize the shards with store recovery steps and then run a round of replication before marking the shards as active. I think we may also need to filter out these allocation Ids from cluster manager updates to the primary, as they should not care about tracking them as in-sync copies.
