Update git submodules

* Update docs/submodules/appc/deployment.git from branch 'master'
  to 78e9b949505245ad8efcdc319107039e333da573
  - Test for working karaf

    Check if the karaf client can be run, and if it doesn not return
    the expected echo value, fail the build since the installs will
    not work in this state.
