Customer has reported APIManager resource does not seem to be able to handle "imageproxy:port/imagename:tag" in the image name, and assumes port is image tag.

in the APIManager resource - they set the image name to use their image proxy - eg 
spec.system.redisImage
images.example.localdomain:5001/rhscl/redis-32-rhel7:latest

Customer recieves the following error:
"error":"DeploymentConfig.apps.openshift.io \"backend-redis\" is invalid: spec.template.labels: Invalid value: \"5001/rhscl/redis-32-rhel7:latest\"
If customer attempts to workaround this by manually creating imagestreams, the operator overrides the system-memcache system-postgresql and zync-database imagestreams back to the original docker.io which is an issue as the customer is in a disconnected environment

This is blocking the customer migrating to OCP4 - is there anything we can suggest?
