Add optimize thread pool (size 1) dedicated to perform explicit optimize API 

Have a dedicated thread pool for explicit optimize calls (shard level optimize operations). By default, the size should be 1 to work the same with how things work currently allowing for only 1 shard level optimize on a node.

The change allows to see the optimize thread pool stats now, and potentially increase the thread pool size for beefy machines.
