Implement Sonar Nexus REST interface directly

The BRMS gateway used the obsolete nexus-rest-client-java library
to query the Nexus repository. This change removes that dependency and
implements an interface directly to Nexus servers using the Nexus
REST interface.

This change is being submitted to ensure that the security issues with the
plugin are resolved. The unit test for the new code will be implemented
in a later submission.
