Shuhei Matsumoto 0b0f0c5415 rpc: Add thread_get_pollers RPC
Add an new JSON RPC thread_get_pollers to retrieve pollers of all
the threads. By adding a helper function spdk_poller_state_str(),
output poller state as string to improve readability. Most of the
code of thread_get_stats and thread_get_pollers are common and so
unify these two RPCs as possible as we can.

Sample output of thread_get_stats RPC in doc/jsonrpc.md was wrong
because thread_get_stats doesn't output ticks. Fix this together.
