https://issues.redhat.com/browse/JBEAP-27067

The EAP 8 guide states that the APPLICATION_NAME env variable is used when creating SAML clients automatically [1] but actually such variable seems to be used by the s2i process ofr OIDC configuration via env variables.
Also, it should be documented the way the value for the client-id attribute configuration is computed [2], because users must create clients accordingly.
