We have been having many issues with external mode with Ceph version mismatching. The operator would have a Ceph version different than the external cluster. The `radosgw-admin` was used to interact with S3 users, even a small version delta would cause the command to coredump. After checking with the rgw core team it appears Rook was misusing the CLI and the admin ops API should be used instead. So this patch is the first introduction of go-ceph in Rook to consume the rgw admin ops API instead of the `radosgw-admin` CLI, **only** for user management in this initial commit. Later we can do more such as bucket operation, zone management etc. Closes: https://github.com/rook/rook/issues/7924 Signed-off-by: Sébastien Han <seb@redhat.com>
