Dev Services for Keycloak provides a limited password grant support

[sberyozkin]

Description

Testing with a password grant (as opposed to the code flow) can be preferred by some users but Dev UI backed up by Dev Services for Keycloak offers a limited support - only those users set in quarkus.keycloak.devservices.users will be recognized - which does not scale at all if a custom realm is imported - not does it really work - who would copy all the users and their passwords from the Keycloak realm into this devservices map property...

It is actually well supported in a Dev UI when the OIDC provider is already started - a password field will be offered and as many users/passwords as required can be tested.

The same should be done with Dev Services for Keycloak - quarkus.keycloak.devservices.users should be restricted to creating the users for the default realm...

Also looks like DevUI for Dev Services for Keycloak misses on the non-devservices related properties changes, ex, client-id - the container does not have to be restarted so the new properties do not propagate to DevUI which needs it to do the code flow redirects etc
