Update git submodules

* Update docs/submodules/snaps from branch 'stable/fraser'
  - Skip searching network in project if external or shared
    
    It meets the OpenStack rules:
      - any router can be connected to an external network.
      - any VM can be connected to a shared network
    
    It completes https://gerrit.opnfv.org/gerrit/59865 which partially
    skip the lookup.
    
    Then CreateRouterSuccessTests passes when the external network is not
    owned by the user running snaps_smoke.
