Update git submodules

* Update docs/submodules/sfc from branch 'master'
  - Merge "Remove get_floating_ips()"
  - Remove get_floating_ips()
    
    get_floating_ips() is non-reusable function, with too much logic
    into it. By using smaller functions, we can compose the same
    functionality and build all tests upon a common set of utilities.
    
    Using the new functions in functest to retrieve the nova ID for a VNF instance,
    it is possible to use a generic solution at the problem of getting floating
    ips deterministcally to the instances
