enhanced spring-application-service.xsd to support Spring profiles
created new azaptree-testing Maven module - discovered that Spring's
AbstractTestNGSpringContextTests was not closing the ApplicationContext
after the test class was done. The application contexts were being
closed at the very end after all test classes were done. This was
causing tests to fail when running using Maven in the
azaptree-security-service project because the max # database conns is
100 and as more unit tests were added, the 100 limit was exceeded -
tests were failing because they could not acquire any more database
connections
