Some Pax Exam integration test utilities.

These classes should make it easier to write some integration tests for karaf based containers.

Things I'm working on: 1. fluent JMX API to connect to a localContainer and run some test. 2. Jolokia API for tests 3. Provisioning of a localContainer based on a profile
