Add support for Fedora-based LiveCD

[gbraad]

Add (experimental) support for a Fedora-based LiveCD:

• https://github.com/gbraad/minishift/tree/fedora
• https://github.com/gbraad/minishift-fedora-iso

Note: Some issues were encountered during the creation of the Fedora-based LiveCD, mostly related to newer versions and changed behaviour. These minor fixes will be backported to the minishift-centos-iso repository.

After adding a provisioner option https://github.com/gbraad/minishift-fedora-iso/issues/1 the deployment now fails with:
