Onboarding upload control

Brings the initial structure to control asynchronously a VSP package
upload during the onboarding.
Instead of blocking the UI, the upload and processing status will be
controlled by the backend, so the frontend can query it and control the
behaviour of the UI.
Updates the upload endpoint to obtain/verify an upload lock, and creates
a second endpoint to check for the upload status.
