[scl.org] Image naming for centos-based images

I think one of the main reason (AFAIK) we used "-rhel7" and "-centos7"
suffixed for the images
was that we simply used one repository ("openshift/") and we needed to have
a way to distinguish
between rhel7 and centos7 images.

Now, when we are pushing the images to "centos/" namespace on DockerHub,
this is not longer required
I think, because "centos/ruby-22-centos7" sounds just weird :-)

Similar to the RHEL7 images that we will ship via registry.access.redhat.com
where we push only RHEL7 based
images, we can relax the suffix.

Are there any other concerns or reasons why keeping the suffixes is bad
other than it "looks weird" and it is
"redundant" ?
