Added @SimplyTimed which doesn’t perform mean and distribution calculations. It only calculates hit count and time spent on a method. @SimplyTimed is a “simple” version of @Timed that reduces calculation time, as these calculations can be performed by Prometheus with the raw data from @SimplyTimed .

The specification now also defines optional metrics specific to JAX-RS invocations. For each JAX-RS method, there is a Simple Timer, so we measure the total count of requests and the total time spent in that method.
