Dynamic CSP rules

Describe the Improvement

It's maybe impossible. But 'impossible is not Directus' Right? 😅
As mentionned [here](

It's hard to figure out how to add CSP rules for live preview functionality.
But in addition to that, I'll add that it's a mess if you're managing multiple blogs, as in a multi-tenant application.
I had to manually write in the docker compose file, stop and start the docker and wait for it to work properly...

Is there any way to add it dynamically everytime users add a tenant / blog or maybe change this rule?

Thank you Rabbits you rocks 🐇 🤘
