When the request thread pool is saturated, it's often useful to know which type request is using the thread pool the most. It would be useful to add a metric per request type that gives us of fraction of the thread pool time (local time) used by that request.
value: Fraction of the time a particular request type spent on the request handler pool.
We will add the relevant metrics as specified in the Public Interfaces section.
