Update git submodules

* Update docs/submodules/sfc from branch 'master'
  - Fix problem to fetch the compute name of client VM

    When migrating to SNAPs a bug was introduced and could be seen in logs as:

    Error when waiting for classification rules: 'module' object has no attribute
     'get_compute_client'

    The cause is that get_compute_client is not a global function anymore but a
    method inside a class. Besides, due to SNAPs, we need to fetch the compute
    name in another way
