[keycloak-dev] Ability to run tests from within Keycloak server added

I've added the option to run pieces of a test from within the Keycloak server. This is useful when you need some details that is only internally available or if you need to execute something on the server. It's pretty simply all you need is to add an Arquillian deployment. This is required to add classes for the code you want to run. An example is added to: https://github.com/keycloak/keycloak/blob/master/testsuite/integration-ar... You can run stuff on the server, fetch stuff from the server and even do assertions on the server which is sent back to the client side. Finally there's some helpers in: https://github.com/keycloak/keycloak/blob/master/testsuite/integration-ar... These makes it easy to fetch internal realm and component settings. We can add more here as needed. Take a look at RealmTest for an example on how to use these. Finally it's pretty nice to use remote WildFly container when writing tests like these. To do that: * Build including dist (mvn clean install -Pdistribution) * Run "testsuite/integration-arquillian/servers/auth-server/jboss/wildfly/target/unpacked/keycloak-3.0.0.CR1-SNAPSHOT/bin/standalone.sh -Djboss.socket.binding.port-offset=100" * In IntelliJ select view -> Tool Windows -> Maven * In the open window expand profiles and select auth-server-remote Now you can run the test and it will use the remote container rather than embedded Undertow.
