This patch introduces the implementation for registering
default policy rules in code. Default rules are defined under
cloudkitty.common.policies. Each API's policies are defined in a
sub-folder under that path and __init__.py contains all the
default policies in code which are registered in the ``init``
enforcer function in cloudkitty/common/policy.py.
This commit does the following:
- Creates the ``policies`` module that contains all the default
policies in code.
- Adds the base policy rules into code (context_is_admin,
admin_or_owner and default rules).
- Add policies in code for current APIs
- Add a tox env to generate default policy sample file
- Delete policy.json from repo as policies in code will be used.
