Add Veeam storage class override (#19748)

Browse Source 
Recent Veeam is very picky about storage class names. Add `_MINIO_VEEAM_FORCE_SC` env var.

It will override the storage class returned by the storage backend if it is non-standard
and we detect a Veeam client by checking the User Agent.

Applies to HeadObject/GetObject/ListObject*
