Bug 1583274

Description of problem:

The documentation at <https://docs.openshift.org/latest/creating_images/metadata.html> states that you can add a LABEL in the Dockerfile named "io.openshift.expose-services" which should name ports when creating new applications.

However, creating a new application with "oc new-app" this information is ignored (at least when using S2I) and only the information of the "EXPORT" keyword is used.

Which results in ports being created nameless.

Version-Release number of selected component (if applicable):

oc v3.9.14
kubernetes v1.9.1+a0ce1bc657
features: Basic-Auth GSSAPI Kerberos SPNEGO
Server https://<myurl>:8443
openshift v3.9.14
kubernetes v1.9.1+a0ce1bc657

How reproducible:


Steps to Reproduce:
1. oc new-project foo
2. oc new-app ctron/s2i-java~https://github.com/ctron/hono-example-bridge

Actual results:

Check "dc/hono-example-bridge", container ports are present but don't have a name.

Expected results:

Port 8778 is named "jolokia". Port 9779 is named "prometheus".
