Handle multiple apps

Makes:

• production app use url: http://$CI_PROJECT_NAME.$KUBE_DOMAIN
• staging app use url: http://$CI_PROJECT_NAME-staging.$KUBE_DOMAIN
• review apps use url: http://$CI_PROJECT_NAME-$CI_ENVIRONMENT_SLUG.$KUBE_DOMAIN

Also uses $CI_BUILD_REF_SLUG in environment name instead of $CI_BUILD_REF_NAME, which may have odd characters (including more slashes).

e.g. foo.example.com, foo-staging.com, and foo-27193-handle-4f99a2.example.com
