Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Change calls to SNAPS library exposing OpenStack instance objects."
  - Change calls to SNAPS library exposing OpenStack instance objects.

    Openstack object structures can change when new API versions are released and
    SNAPS no longer is exposing OpenStack object implementations as this makes
    the library brittle. The only two SNAPS method calls affected are when functest
    needs to query for external networks and when vPing Userdata needs to obtain
    the console logs.

    JIRA: SNAPS-125
