Description

Currently changing the size of threadpools is done using the config files. If resizing a threadpool, the node needs to be taken offline.

Adding resizing via JMX allows online tweaking. TPEs allow for moving the number of threads up and down; moving down will take effect after a thread in the pool becomes idle.
