Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Last task necessary to stop users from easily obtaining OS objects.

    Changed external interfaces still exposing OpenStack created APIs to
    either return SNAPS-OO domain objects or objects contained on the
    OpenStack generated objects as to not leak implementation details that
    would eventually break the library when new API versions are released.

    JIRA: SNAPS-125
