Add support for JMX operations

Most of the JMX datasources I've seen use Groovy, which might be a better way to go (or only way until/if this is changed in the JMX data type).  I checked the full list of references to jmx: from one of our portals -- list below.

The LM supplied JMX classes for Groovy don't support bean operations, at least not as far as I can tell.
