Fix more OS-DCF:diskConfig XML handling

Add handling in the deserialisation code to handle the
OS-DCF:diskConfig attribute in the rebuild and resize actions so
the diskConfig extension can handle it properly. Formerly only
the older auto_disk_config attribute was managed (and incorrectly so).

Return error details to users in "dns-create-private-domain"

Fixes bug 1135539
When SysLogHandler is configured in UDP socket mode, the user
who doesn't have the admin privilege got the unexpecting internal
server error(HTTP 500) in "nova dns-create-private-domain" command.
This bug occurs as the call graph drew below:

|--ProxyCallback._process_data():amqp.py
                          |--LOG.exception()
                          |    :
                          |    |--BaseHub.switch():hub.py
                          |                 |-- clear_sys_exc_info()
                          |
                          |--ctxt.reply(None, sys.exc_info(),..)
                                       |
                                       :
                                       |
                         |--serialize_remote_exception():common.py
                                       |--failure_info#(None,None,None)

The sys.exc_info() is cleared by the clear_sys_exc_info(), but it is
called again by the ctxt.reply().
This patch prevents the internal error and returns the details of
the forbidden error(HTTP 403) which is expected.

Prevent volume-attach/detach from instances in rescue state

Rescue is supposed to just be a way to log into a wayward instance
if something goes wrong with the base image that may have had some data
(logfiles etc.) and make it possible to grab that  - block devices are
assumed to be accessible by re-attaching them, and are considered
persistant so no need for rescue there.

Since there is no need to attach a volume in rescue mode, and detaching a
volume that was previously attached doesn't work, just ban volume
attach/detach in rescue state.

Fix RequestContext crashes w/ no service catalog

Code introduced in a prev review assumed service_catalog will be
at least an empty list and will never be None.  But missed one code
path where the service_catalog could potentially be set to None. So
this change switches back the default value of service_catalog in
the arguments to None and makes sure we tolerate anyone else
passing in a None or Empty list as service_catalog

Enable tox use of site-packages for libvirt.

Enable the use of site-packages in tox which will allow the use of the
system install of libvirt while testing.

Hardcode the libvirt host UUID for tests that check this UUID when
system libvirt is being used. Without this hardcoding eight tests
would fail when using the system libvirt install.

Partially fixes bug #1113181

Ensure that headers are returned as strings, not integers.

The 'Retry-After' header was set as an integer, and it was causing that
mod_wsgi failed with a 500 error, instead of the actual error. This
ensures that the headers are converted to str.

Fix multiple fixed-ips with quantum.

This patch fixes a bug in the quantum suppot where multiple requested
fixed-ips did not work.  Every network interface would be given the last
fixed IP that was specified.  The problem was just the lack of putting

Found bug 1156227 in sqlite we have lost UC on virtual_interfaces.address
