A class to build point-to-point operations for batch_isend_irecv.

Args mirror torch: op is [isend()](tensorplay.distributed.distributed_c10d.isend.html#tensorplay.distributed.distributed_c10d.isend) or [irecv()](tensorplay.distributed.distributed_c10d.irecv.html#tensorplay.distributed.distributed_c10d.irecv), peer
is a global rank (or group_peer a group rank).
