As per the community goal of migrating the policy file 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 project side via warning in doc and format releasenotes. 1st item if already done by cinder in Stein so this commit only cover the 2nd item. Since oslo.policy 3.6.0, by default oslo policy will fallback to existing policy.json file to give operator some time to migrate it to new default policy.yaml. But cinder already changed the default value to policy.yaml long back since Stein so no need to fallback to default JSON file. To do that it disable this fallback via flag to oslo.policy. Also convert the tests/unit/policy.json to policy.yaml file. Additionally, made some corrections to outdated documentation when removing references to a "policy.json" file.
