Performance tools such as nvme-perf may want to
create lots of qpairs to measure scaling, and then
want to set async_mode = true to amortize the
connection cost across the group of connections.
But we don't want connections to be connecting
in the background while we are doing I/O. So add
a new API spdk_nvme_poll_group_all_connected to
check if all of the qpairs are connected.
