User is stuck in login loop if Keycloak is misconfigured on Quarkus

[mmuzikar]

When Hawtio is configured to use Keycloak there is no information for the user that something is wrong with the configuration / services and the issue is not strictly due to their invalid password.

This is what happens when a keycloak instance is not running on Quarkus:

For springboot with the same setup there's a redirection failure

It would make sense to tell users that the service is down so they are unable to login.

@mmuzikar The login page shouldn't show up when Keycloak is enabled. I suspect it's an issue with browser cache. Do you use Incognito mode and still see the same issue?

This happens when quarkus-oidc extension is not added to the project. When quarkus-oidc is added a normal error page is shown when keycloak is not running.
