Fixes spawn method signature for PowerVM driver.

ComputeDriver has now 2 new required arguments which are:
injected_files and admin_password. This patch adds the
arguments in the PowerVMDriver spawn signature.

Update nova-rpc-zmq-receiver to load nova.conf.

Updates the bin/nova-rpc-zmq-receiver so that it makes use of FLAGS,
calls parse_args, and loads the nova.conf config file like all
other nova- binaries.

fix issues with Nova security groups and Quantum

bug #1039400

- make quantumv2/api.py fetch actual DHCP server address, which
is needed by firewall layer (otherwise, the gateway IP is
incorrectly used and all DHCP traffic is dropped).
- add missing call from quantumv2/api.py to the security
groups API when a VM is allocated/deallocated.

- Add a vif-driver that is a hybrid of the existing Open vswitch +
linux bridge drivers, which allows OVS quantum plugins to
be compatible with iptables based filtering, in particular, nova
security groups.

- Also clean-up some docstrings in virt/libvirt/vif.py

On rebuild, the compute.instance.exists

notification should contain the original image
metadata.

In order to do this, the original system metadata associated
with the instance is preserved and passed along to the
rebuild_instance() in the compute manager.

(Code originally from Iccha Sethi and Rick Harris.)

Add full python path to test stubbing modules for libvirt

libvirt test modules were relatively addressed (import fakelibvirt etc.)
and this meant that running the test specifically
(./run_tests test_virt_drivers) would fail with missing imports.

Fix hyperv driver spawn() signature

Fixes bug #1045392

commit 99fb9d2a changed the signature of the spawn() method but not
all drivers were updated for the change.

The injected_files and admin_password instance attributes were ignored
by the hyperv driver before, so we can just ignore them in spawn() now
that they are being passed as function arguments.
