Implement basic uploading of material

Steps involved are:
- Create an archive of all materials.
- Request the cloud API to provide a URL to upload the archive to.
- Upload the archive to that API.

Currently the two internet requests are asynchronous, meaning that the job will 'end' before the upload is complete. Most likely the job instance will even be deleted before we get a response from the server. So this won't work, really. Need to structure that a bit differently. But I want to save this progress because it embodies the happy path well.

Contributes to issue CURA-8609.
