installed.

Disable VirtualBox USB2.0 controller
Add another NIC to the box

We're using teaming by default now. So we need two NICs for the admin network.
Fix controller's network config

- Addtional Interface for bonding
- add ifcfg file for the admin network to the kiwi image
- disable default folder sync
Only add a single CPU to each VM

Most user will probably not have quad core machines and we're starting enough
VMs to keep the system busy anyhow.
Run crowbar_register on the controller

This requires some fixes to the provisioner barclamp:
- Some of our repos are unsigned call zypper ref with --no-gpg-checks
- crowbar_register doesn't work when the admin network is not on eth0
  (crowbar/barclamp-provisioner#302)

Networking fixes and preparations for crowbar_register
Create shared disks for SBD, cinder and glance

The drbd disk was to wait a bit until we figured out howto switch to SATA/SCSI
or add another IDE controller. The compute nodes don't need additonal disks.
Removed the comment regarding that.

Thanks bgeuken for help with this!
shrink cinder/glance shared disks from 5GB to 1GB

Shared disks have to be preallocated, so this slows down initial boot-up
and increases spare disk requirements.
