The checks performed by this script aren't always useful to downstream
consumers of the repo so allow them to disable the script without having
to make changes to tox.ini.
We use the $commit_hash variable for the check for stable-only patches,
else it will incorrectly fail because it is checking the merge patch's
commit message.

As Cyborg is switching to new policy, this is required
to avoid breaking the existing deployment using policy
file in json format and relying on default value of
'CONF.oslo_policy.policy_file'.
Default value of 'CONF.oslo_policy.policy_file' config option
has been changed from 'policy.json' to 'policy.yaml'. If new default
file 'policy.yaml' does not exist but old default 'policy.json' exist
then fallback to use old default file.
An upgrade checks is added to check the policy_file format and
fail upgrade checks if it is JSON formatted.
Added a warning in policy doc about JSON formatted file is deprecated,
also removed all the reference to policy.json file in doc as well as
in tests.
