Try to avoid hard-coding the 8091 port

We already have an attribute for this.

There are still hard-coded usages, but this commit is a first step.
Remove unused provisioner_ip template variable
Add openstack-keystone Should-Start in SUSE init script for crowbar_join

crowbar_join will call chef-client; if this is happening on a controller
node, then the server roles for glance/cinder/quantum/nova will try to
contact the keystone API. But this one won't have started yet since the
keystone cookbook will only restart it delayed (unless the config file
changed, which won't happen on boot).

So we need to have keystone running before.
Add openstack-neutron Should-Start in SUSE init script for crowbar_join

Similarly to previous commit, we need an openstack-neutron dependency
because the cookbook will contact the neutron API which might not have
been started by the cookbook.

use the full ssh comment as key

Otherwise, if several keys with the same hostname (a@foo.com, b@foo.com)
are used, only the last is stored.

Pessimize usb devices when determining boot device

Otherwise it believes that this machine is booted via floppy:

pci-0000:00:1a.0-usb-0:1.4:1.0-scsi-0:0:0:0 -> ../../sr0
pci-0000:00:1a.0-usb-0:1.4:1.0-scsi-0:0:0:1 -> ../../sde
pci-0000:00:1a.0-usb-0:1.4:1.0-scsi-0:0:0:2 -> ../../sdf
pci-0000:00:1f.2-scsi-1:0:0:0 -> ../../sda
pci-0000:00:1f.2-scsi-2:0:0:0 -> ../../sdb
pci-0000:00:1f.2-scsi-3:0:0:0 -> ../../sdc
pci-0000:00:1f.2-scsi-4:0:0:0 -> ../../sdd

Change it into a two pass approach, first ignoring usb, then going over
all devices.
