Support web storage in JMX plugin This commit fixes the JMX plugin to work with web storage. Aside from needing a command channel action and associated role, there were a few other issues this commit addresses. Most importantly, I noticed the GUI would hang when trying to enable JMX notifications without proper permissions after the third attempt. This seems to be due to another issue where the web service stops responding to the client's requests. I traced the hang down to waiting on the network for AgentInfoDAO.getAgentInformation. I've fixed the GUI hang by making the toggle notifications action asynchronous, running in an executor provided by ApplicationService. Another fix in this commit is provided feedback to the user when authentication fails when trying to toggle JMX notifications. This is done using a dialog box similar to the thread plugin. One final small fix is to add the jmx-common bundle to the webservice command in thermostat-plugin.xml. Without this, the webservice cannot find the JMX storage entities it needs.
