This authenticator should be similar to [JaasAuthenticator](https://github.com/rhuss/jolokia/blob/282f8e1b62fb503cfc5360fcfcdec66e3f630267/agent/osgi/src/main/java/org/jolokia/osgi/security/JaasAuthenticator.java) but should be able to participate in an OAuth2 SSO. The JVM agent should contain extra options to enable this.
