Code Issues Proposed changes

s3token: Fix Keystone API configuration 

Upstream removed the api_version configuration option and started
to expect the version to be encoded in the Keystone URL at Rocky.

Add S3 API functional test.

Remove invalid configuration items in the s3token section.

Remove configuration templates for OpenStack versions prior to
Mitaka.
