Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Configure physical_network when creating network

    When the network_type is vlan, configuring physical_network
    and segmentation_id should be supported by snaps.
    Here only testcase test_check_vm_ip_dhcp is changed, which is
    consumed by functest.
