Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Fixed problems when setting the OpenStack project ID.

    There were several calls to retrieve the project ID that required
    named parameters which was causing the utility function to always
    return None. Additionally, when creating the dict() required by the
    Neutron create API 'body' parameter key 'project_id' is not supported
    and still uses 'tenant_id'.

    As these problems should have been found earlier, this patch also
    extends the tests for networks, subnets, ports, and security groups
    to use 'tenant_id' rather than 'project_id'.
