This is a follow-up to https://gitlab.com/gitlab-org/gitlab/-/issues/23345
Today installing GitLab requires [up to 13 different
buckets](https://docs.gitlab.com/ee/administration/object_storage.html#storage-specific-configuration),
this adds a lot of friction to new installations as well as slowing
down feature adoption.
Thanks to [consolidated object storage
configuration](https://docs.gitlab.com/ee/administration/object_storage.html#consolidated-object-storage-configuration),
developed in https://gitlab.com/gitlab-org/gitlab/-/issues/23345 we
now support one single credential for all the buckets.
The next step will be to use just one bucket.
