kie-server: move test config into common base class
kie-server: use custom settings.xml in tests

 * for now just declare the Maven repo in target/ so the
   tests are deploying kjars there. This way we can
   be sure everything that is needed for tests is
   properly prepared as the target/ dir will be removed
   before running the tests. Deploying to ~/.m2 may lead
   to situations where locally the tests are passing, but
   on CI server they fail (the artifact is in local repo,
   but not in the repo of the CI server)
kie-server: move the container CRUD tests into own class
kie-server: no need to store the testing kjar in target/
