AS7 I-test work, add back nonpc tests
also:
 - add back disabled test in GenericJBossAS7PluginTest after ensuring
   all discovered components gets a chance to start.
 - alter execution order to run GenericJBossAS7PluginTest first because
   prior test executions seemed to mess up an expected trait metric
 - pull up code in AbstractAgentPluginTest to GenericJBossAS7PluginTest,
   it's only caller.
