Patch to allow maven validator plugin to load dependency plugins

Description of problem:

Plugin Validator Maven plugin does not support validation of plugins that depend on other plugins

How reproducible:

Everytime

Steps to Reproduce:
1. Create a plugin that depends on another plugin, for example JMX
2. Add plugin validator maven plugin to project POM
3. Validation fails due to required plugin JMX not being loaded in the test plugin container
  
Actual results:

Error from plugin validator

Expected results:

The dependency plugin should be added to the maven pom, and the plugin validator should be able to load it. 

Additional info:

A patch for the validator is attached, which looks for other RHQ plugins, and loads them in the test plugin container.
