Since version 9, the `koji-osbuild` plugin supports specifying upload
options as part of a Koji build. This enables one to upload the built
image directly to the cloud environment as part of the image build in
Koji.
Extend the configuration schema with `upload_options`.
Extend the documentation and describe valid `upload_options` values.
Add a unit test testing a scenario when `upload_options` are specified.
