To support resize operations during I/O, we will need
to send messages to each thread to quiesce I/O while
the resize operation is in progress to guard against
the cluster map memory changing while another thread
is accessing the cluster map.
Therefore, spdk_blob_resize needs to be asynchronous.

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
