Description

We should add a reset operation to the Metrics MBean, which will set all the counters to 0.

Note: Deleting the counters from the map of attributes was not suggested because that could break any scripts that get the list of attributes from the bean and then the values of each attribute. Also, 0 is unlikely to be an actual value for any counter, and it will not break the increment functionality.
