be included in every PATCH response if the upload is going to expire. Its value MAY change over time.
If the expiration is known at the creation, the Upload-Expires header MUST be included in the response to
the initial POST request. Its value MAY change over time. The value of the Upload-Expires header MUST be in
RFC 7231 (https://tools.ietf.org/html/rfc7231#section-188.8.131.52) datetime format.
