Add sample file generation script and helper methods1.9.0

This adds a console script to oslo.policy that will output a sample
policy file in yaml format. It works by looking at the configured
namespace(s) under an 'oslo.policy.policies' entry point. A method, or
methods, should be provided which return a list of
oslo_policy.policy.RuleDefault objects.

To use this script add an entry to setup.cfg in a project with something
like:

oslo.policy.policies =
    nova.api = nova.api.opts:list_policies

list_policies should be a method which returns a list of
oslo_policy.policy.RuleDefault objects.

Then run it like:

oslopolicy-sample-generator --namespace nova.api

--output-file can also be specified, or those options can be configured
in a file which can be specified with --config-file.
