Update git submodules

* Update charms.openstack from branch 'master'
  - Override subprocess environment for dpkg
    
    Whenever we subprocess out from the charm, it is most likely because
    we are running tools provided by the payload to mange it.
    
    We should take care to set an appropriate environment whenever there
    is a chance for external python tools to be directly or indirectly
    involved.
