Poc broken billing

[wejdross]

This is Proof of Concept to make discussion easier. Why it happened:

• if someone creates vshn service like postgresql, mariadb etc. and triggers a backup, for example using cron * * * * * and then deletes everything - claim, backups, namespace etc. we end up in state where we receive bill fot services but we're unable to match it with actual customer. We just receive info from Cloudscale that there are billing records for bucked named XXX owned by non existing UserID "some_long_id"

How it's supposed to work:

• as You can see I'm introducing possibility to send an event (auth tbd) from DELETE webhook of our providers providing S3 - If You want to delete, I must ensure it's completely billed otherwise I block deletion

It's still going to pop up in our logfiles, which I'm fine with, as long as we make sure there's an accounting record in the database.
