Make "noop" request breaker a non-dynamic setting

The issue with making it dynamic is that in the event a cluster is
switched from a noop to a concrete implementation, there may be
in-flight requests, once these requests complete we adjust the breaker
with a negative number and trip an assertion.
The issue is if it is a noop breaker, we can't run any of the circuit breaker tests, should I add a change that tries to detect the type of breaker and skip the tests if it's a noop breaker?
