Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Refactored SNAPS tests to take in the actual OSCreds object.

    The code previously had individual parameters for different
    aspects of the credentials. This change not only makes the
    method calls easier, but it also helps the logs from becoming
    too verbose as each test case was instantiating its own OSCreds
    instance.
