For people using freezer it might be useful to retrieve api-paste
file with package rather then looking for it in the repo.

Setuptools v54.1.0 introduces a warning that the use of dash-separated
options in 'setup.cfg' will not be supported in a future version [1].
Get ahead of the issue by replacing the dashes with underscores. Without
this, we see 'UserWarning' messages like the following on new enough
versions of setuptools:

  UserWarning: Usage of dash-separated 'description-file' will not be
  supported in future versions. Please use the underscore name
  'description_file' instead

As per the community goal of migrating the policy file
the format from JSON to YAML[1], we need to do two things:

1. Change the default value of '[oslo_policy] policy_file''
config option from 'policy.json' to 'policy.yaml' with
upgrade checks.

2. Deprecate the JSON formatted policy file on the project side
via warning in doc and releasenotes.

Also replace policy.json to policy.yaml ref from doc.
