Update git submodules

* Update docs/submodules/daisy from branch 'master'
  - Exit if kolla image build failed

    Previously, image build failure was ignored since the failure is
    caused by images that we do not need. Then, we only build what
    we really need. So now, image build failure should not be ginored
    any more.

    This PS also do clean up task after failure occured, althrough
    this is  not really necessary when running in a temporary VM. But
    it is helpful when running manually.
