Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Delete 2 sub test cases from patrole

    These 2 test cases failed on OSP10 with reasons
    1. Provided object does not match schema 'image': u'shared'
       is not one of ['public', 'private']
    2. Provided object does not match schema 'image': u'community'
       is not one of ['public', 'private']

    'shared' and 'community' was added in the Image API v2.5
