This will be used to track time used in pollers - each poller can now
indicate if it found any work to do or not.
For cases where it was obvious and the infrastructure was already in
place, existing pollers have been modified to return 0 or a positive
value to indicate whether work was done. Other pollers have been
modified to return -1 by default, indicating that the poller isn't
indicating anything about whether work was performed. This will allow
us to find un-annotated pollers easily in the future and fix them
incrementally.

With multiple core bining for NVMe-oF target,
the qpairs which belonging to the same ctrlr may
be scheduled to different cores. Thus there is
resource contention to access the struct spdk_nvmf_ctrlr.
And we put the thread info in polling group. Morever,
we introduce an admin_qpair in ctrlr. Since admin_qpair will
always be created at first and freed at last, to reference
this pointer is safe.
