Switch Vagrantfile.example and documentation to use vagrant-sshfs instead of NFS
There's a package review for getting vagrant-sshfs into Fedora that I plan to help get in rapidly:
Once it's in Fedora, Pulp's Vagrant setup would be greatly simplified by using that instead of NFS (no firewall rules, no permissions issues!) All that would be needed is cleaning up the docs to not mention the NFS stuff, to tell users to install that plugin, and to update the Vagrantfile.example to use it instead of NFS. Of course, users who want NFS can still craft their own Vagrantfile if they like.
