#4151 [HHQ-4012] Need a formal way to programmactically deprecate

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4012
Need a formal way to deprecate plugins instead the hacky "just remove autoinventory from the plugin descriptor"

This mechanism should include removing any Resource Types that are in the DB that aren't associated with any active Resources.

An idea for this is to update our plugin schema to include a new attribute for the plugin tag.

For example:

<plugin deprecated="true">


...


...


</plugin>

When the server or agent loads this plugin it will ignore it completely and remove any reference to it unless there are resource types are active.
