JBIDE-13639 remove struts tests from integration-tests

Because struts is no longer present in JBT master, I am removing
it from integration-tests as well and all references to it.
Hibernate RedDeer plug-in added with initial Hibernate Console support
New AnnotationPropertiesTest implemented
Fix for CDIValidatorTest.
Sleep method added for CDI Validator to have enough time to validate
observers
