Install glusterfs-fuse to allow mounting of Gluster Volumes

[nixpanic]

Gluster is one of the commonly used backends for dynamically provisioned PVCs. In order for pods to use the PVCs, these need to get mounted on the host. The glusterfs-fuse package is needed to provide the mount.glusterfs helper and dependencies.

Please install the glusterfs-fuse package in the fedora.template.

@nixpanic do you see any value addition if we add glusterfs-fuse package for minishift iso side? I mean this is going to be a single node cluster and we use the PV which is created by oc cluster up. If you can provide a use case for this, we can add it. If you want to use current iso then take it from http://artifacts.ci.centos.org/minishift/minishift-centos-iso/pr/11/ .

Yes, we have users testing with minikube/minishift if dynamic provisioning with Gluster is suitable for them. It is possible to deploy Gluster on a single-node, it is just not useful for high-availability.

A related change in minikube was merged a while back: https://github.com/kubernetes/minikube/pull/2925

I'm working on an add-on for minikube at the moment. Once the container images support a simpler way of getting deployed, I'll send it as a PR. After that, I plan to do the same thing for minishift.

The centos image does indeed not have the glusterfs-fuse package either. It would be good to add it there as well. That needs a 2-step installation process though:

1. yum install centos-release-gluster
2. yum install glusterfs-fuse
