ELY23019: Invalid ID token

A Docker Compose test environment was created for WFL-16000 , and this test case also demonstrates this Invalid ID token issue.  The test environment can be found here:  https://github.com/slominskir/wfly16000   The easiest way to reproduce is to use the Docker test environment.  However, to manually reproduce you'll need to install Keycloak and configure it with a frontend URL that differs from the backend URL.  Wildfly then needs to be configured using the provider-url instead of the auth-server-url .  A simple application (.war file) then must be created that triggers auth.  Deploy the application, navigate to the webpage to trigger auth, and watch the logs after a successful auth.
