Bug 1628968

Description of problem:
When browsers from other hosts access the web console of an `oc cluster up` server, the url must prefix with /console, otherwise it redirects to https://127.0.0.1:8443/console, which makes access fail

Version-Release number of selected component (if applicable):
oc v3.11.6

How reproducible:
Always

Steps to Reproduce:
1. # oc cluster up --image='brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/openshift3/ose-${component}:${version}' --public-hostname=10.8.250.232
2. Access https://10.8.250.232:8443 from other hosts
3. Access https://10.8.250.232:8443/console from other hosts

Actual results:
2. Redirect to https://127.0.0.1:8443/console, which makes access fail
3. Access succeeds

Expected results:
2. Access succeeds.

Additional info:
# oc get cm -n openshift-web-console webconsole-config -o yaml

I know it shows "consolePublicURL":"https://10.8.250.232:8443/console/". But this should therefore require we must input with /console in address bar. Because, let's compare to ansible-installed OCP clusters, they also shows "consolePublicURL":"https://xxx:8443/console/", but access to them without /console CAN work well. So oc cluster up should address the problem. It quite confuses me a lot at the beginning.
