Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Merge "Created domain classes for security groups."
  - Created domain classes for security groups.
    
    Created SecurityGroup and SecurityGroupRule classes so the neutron_utils
    for security groups will be returning objects of these types instead of
    the OpenStack objects returned by the API calls.
