Alex Kavanagh 9c12812735 Switch the charm to support py3
Some major changes:
* the charm has been rebased (from a Python perspective) to be rooted in
  the charm directory.  This is a single root.
* Imports have been changed so that the don't add lots of imports to the
  namespace of the module doing the import.
* The code that used to run at module import time has been made lazy
  such that it only has to run if the relevant functions are called.
  This includes restart_on_change parameters, the harden function and
  the parameters to the guard_map.  Appropriate changes will be
  submitted to charm-helpers.
* Several tests had to be re-written as (incorrect) mocking meant that
  text fixtures didn't actually match what the code was doing.  Thus,
  the tests were meaningless.
* This has had a net positive impact on the unit tests wrt to importing
  modules and mocking.
