initial commit for groovy integration REST tests

The motivation is to simply the REST tests and make them more self-documenting.
use standalone-test.xml, switch to junit, and make default UIR configurable
forgot to include wildfly config files in previous commits

Also trying out just runnung maven once in the travis build
started porting some additional tests

I ported a few additional tests from BaseTest.java, but decided to hold off on
any more becaue the end points used in the tests are going to be removed.
clean up .travis.yml
remove whitespace from blank to make checkstyle happy
revert changes to .travis.yml since maven is going to run twice any ways
Merge pull request #78 from rhq-project/rest-tests
