[keycloak-dev] Strip default port from URLs in KeycloakUriBilder

I've sent a PR [1] that strips default ports (80 if http, 443 if https) from the URL in KeycloakUriBuilder. This is to make sure URLs matches URLs in browsers (browsers already do this) and also strips default ports from adapter configs which resolves [2]. [2] although strictly bad config is nice to be able to do if you have a keycloak.json file that takes the port from environment variables to for instance run on 8080 in test and 80 in prod. Anyone have any concerns with this PR? [1] https://github.com/keycloak/keycloak/pull/4774 [2] https://issues.jboss.org/browse/KEYCLOAK-5945
