Update git submodules

* Update docs/submodules/snaps from branch 'stable/fraser'
  - Removed project query restriction when looking up network for port creation.

    When creating a router to an external network, the port configuration object
    was performing a lookup using the port's user and project ID; however, as
    external networks created in other projects and are visible amongst all
    projects can also be added to a port. This patch removes the project restriction
    from the network query. I do not believe this fix should ultimately break other
    functionality as networks that cannot be looked up by a certain user would
    still return None raising a valid exception.
