Part of the OidcWithDeploymentConfigTest test case verifies a server running at default stability level and other parts are only required for Preview. This Preview feature was introduced in https://issues.redhat.com/browse/WFLY-16532 but now it is being promoted to Community stability level via https://issues.redhat.com/browse/WFLY-20037

The test class should be split into two parts. The ultimate goal is to have a base test testing all that is available at Default stability level, and an additional test that verifies anything outside of Default stability level. This test should use a ServerSetUpTask available from https://issues.redhat.com/browse/WFCORE-6728 that makes the server to be reloaded to a certain stability level if such a stability level is supported by the server under test.

Actually, this test uses a ServerSetUpTask to reload it under Preview, but is incorrect since if the server under test does not support Preview, this ServerSetUpTask is supposed to skip the whole test case, losing the required coverage for Default stability level.
