Provide file size and an arbitrary name to the upload request

Browse Source 
Apparently the Cloud will need to know the file size before it gets uploaded. It is used as a redundancy code to verify that it's not corrupt there.
Perhaps they should ask for a CRC instead, being more reliable against an upload containing only null bytes or whatever, but that is not up to me to decide.

Contributes to issue CURA-8609.
