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

[Stian Thorgersen]

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?
