Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Proposing to move "post conditions" as an optional topic for a test case.
    
    It is not clear that there are post conditions to be documented for all test cases.
    In the case a test cse creates an image and deletes it, there is littöe need for
    a post condition to be documented.  If a test case establishes a network to be
    used for a subsequent test ina  sequence this information should be clearly dcumented.
