convert Vagrant provisioning environment to run on bare metal
appliance only: remove -v from install-suse-cloud

We only need -v in the Vagrant context, since STDOUT is not an
interactive tty.
appliance only: disable SBD

With Vagrant, we can guarantee an SBD device is available.
appliance only: allow two storage options: NFS and DRBD
appliance only: fix crowbar_register

This fix is not needed for the Vagrant environment, since there is
only one NIC on the admin network.
appliance only: restart apache2 after installation?!
appliance only: add in YaST firstboot script
appliance only: add fix-chef-client-when-cluster-down.patch

See https://github.com/crowbar/barclamp-pacemaker/pull/149

Not yet sure if this helps.
