Michael Piszczek 29c0e0dc3e thread: add spdk_poller_get_id
Issue: spdk_top tracked pollers by the poller name string and the
thread_id they are running on. This shows incorrect stats when
multiple pollers exist on the same thread with the same name.
Solution: Added a unique poller id for each poller on a thread and
to allow spdk_top to track pollers by thread_id and poller_id.
