Introduce a new parameter in jmx servlet to exclude the specific mbean

There are many regionservers serving over a thousand regions in our company, and the metric load is pretty big.
I tried to exclude some huge mbean like 'Hadoop:service=HBase,name=RegionServer,sub=Regions' with regex, but didn't succeed.
So I want to propose a new parameter 'excl' in jmx servlet to exclude the splecific bean or beans.
