SOAP-1053 - Implement basic configuration gui for OAuth 2.0
Add FEST test for OAuth2 Basic configuration GUI (these are ignored for now since they don't work well when running all together. Will look more into this)
Refactor production code affected by the above tests to be testable, by giving name to components.
Refactor the FEST tests and add common set of utility classes to be used in the future.
Clean up old tests not being used.
Clean up system test pom file and release it from the Maven integration-test phase so it's not built by default.
Refactor the RequestAuthenticationInspector into a hierarchy of inspectors based on request type
