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 and tests.
