OpenStack: Remove volumes from limits tests.

OpenStack Grizzly no longer supports volumes. This removes
the volume settings from the OpenStack limits tests and Mock
.

This change has will has no effect on users of previous of
Fog for previous releases (Folsom, etc) but should allow
us to easily support the latest upstream codebase and run
Fog *real* tests.

OpenStack: Remove volumes from limits tests.
OpenStack: updates to quota tests.

Updates to the OpenStack quota tests to support the latest
changes in Folsom/Grizzly. With these changes I am able to run
the *real* tests again with the latest upstream OpenStack builds.

This change has no functional effect on Fog users for previous
releases of OpenStack (Folsom, etc,) but should allow us to
support the latest upstream codebase and run Fog *real* tests again.

Merge pull request #1325 from dprince/openstack_quota_test_fixes

OpenStack: updates to quota tests.
OpenStack: security group test fixes.

Update the OpenStack security group test to support the correct
format for create_security_group responses. This patch
removes the extra [] wrapping the response and makes it so the
real tests run once again.

Also updates the existing Mock for create_security_response so
it handles it properly as well.
