JBIDE-18794 add jbosstools.test.jre.* properties and set skipITests=true by default >> master

Suggestion:
<!-- default properties for Java runtimes to be used and set during testing. These properties will be set when running on jenkins, but you can set them in your settings.xml to avoid having to set them manually on every run. Not supposed to be set in your pom's since they are machine specific. -->
