[BZ 1026473] When upgrading bundle with compliance=full deployment folder

As we now handle directories in bundle, directory name 'test' wouldn't match
pattern 'test/.*' (which is 'rhq:ignore test/**'). Fixed by adding trailing
slash when evaluating match.

Show IPCE messages in the resource errors popup

Since commit e460fc84, IPCE messages were no longer displayed, leaving the user with a generic resource error message
as7 itests: re-enable and fix ManagedServerTest
as7 itests: wait for inventory to stabilize before testing update resource config methods

If you call loadUpdateResourceConfiguration too early, there will be very few resources commited in inventory.
Add dynagroup expression template for RHQ Agents
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.
