Drop libvirt qemu configuration

This configuration fix with regards to cgroup ACL should go to the
puppet-nova module instead. With latest OpenStack Network architecture
there are valid setups to use this module dedicated for the network
part without any compute service, like libvirt, runnin on that node.

This got introduced due to this bug:
https://bugs.launchpad.net/openstack-cisco/+bug/1086255

I guess the issue is/was that /dev/net/tun access is missing by default
for some distribution. Which is required if OVS is used and needs to
be configured by libvirt.

But such fix should go to puppet-nova or a libvirt puppet module instead.

Don't rely on Array.to_s which differs between Ruby 1.8 and 1.9

The should contain_quantum... call is relying on the stringification
of params bridge_mappings/bridge_uplinks arrays for a successful match.
With ruby 1.8, this currently works by accident since the array only
has 1 value and is stringified to something like 'default:br-ex'.
With ruby 1.9, it is stringified to '[default:br-ex]' causing the
match (and therefor the tests) to fail.

This patch bypasses the differing to_s implementations by just
calling join(',')

Fix @property_hash creation in custom types.

 * @property_hash for the network, subnet and router types was
   previously being created by referencing values in a hash indexed
   by strings, but using symbols to do so.  This patch ensures
   that strings are used to reference values in the hash.
