Updates across the charm and unit tests to switch to execution under Python 3. Note that the changes are not backwards compatible with Python 2. Refactor use of neutronclient python module to simply wrap the neutron binary, using the yaml output format to avoid the requirement for a Python 3 module on older OpenStack release versions.
