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. Change-Id: Id07d9d1caaa9b29453a63c2e49ba831071e9457f
