Add fedora image

[omron93]

Try to add Fedora image - related to https://bugzilla.redhat.com/show_bug.cgi?id=1483467

But Fedora testing with https://github.com/openshift/ruby-hello-world is failing for Fedora.

@pkubatrh @hhorak @uhliarik Any idea where could be a problem?
Also I see that passenger SCL is EOL, do we want to have Fedora container?
