Title: Added thread pool cat api

Added dedicated thread pool cat api, that can show all thread pool related statistic (size, rejected, queue etc.) for all thread pools (get, search, index etc.)

By default active, rejected and queue thread statistics are included for the index, bulk and search thread pool.
Other thread statistics of other thread pools can be included via the `h` query string parameter.
