Assign partitions for this client to handle for the specified subscription.
The client must send an InitialPartitionAssignmentRequest first.
The server will then send at most one unacknowledged PartitionAssignment
outstanding on the stream at a time.
The client should send a PartitionAssignmentAck after updating the
partitions it is connected to to reflect the new assignment.
