Description of problem:
RHCS 4 release notes state that we added support for S3 MFA-Delete
With this release, the Ceph Object Gateway supports S3 MFA-Delete using Time-Based One-Time Password (TOTP) one-time passwords as an authentication factor. This feature adds security against inappropriate data removal. You can configure buckets to require a TOTP one-time token in addition to standard S3 authentication to delete data.
However , details on how to use it is not added to our documentation in Object Gateway guide.
