1. `rank` and `world_size` are now available on `ReplicaContext`. 2. Replica initialization now requires providing a rank 3. Any change to the replicas rank will be communicated from controller via `.reconfigure()` method. 4. Assigned rank to replica can be fetched from `get_metadata()` function, this will be useful during controller recovery to reconstruct the state. This PR fills in a dummy rank value, in the future PR we will fetch the replica from DeploymentRankManager and pass in the correct value.
