Pass executor name to request interceptor to support async intercept calls (#21089)

Today the request interceptor can't support async calls since the response
of the async call would execute on a different thread ie. a client or listener
thread. This means in-turn that the intercepted handler is not executed with the
thread it was supposed to run and therefor can, if it's executing blocking
operations, potentially deadlock an entire server.
