Deleting a(n) (image) paste doesn't seem to work on ptpb.pw

[MacGyverNL]

As in the title, deleting a paste per the documentation doesn't seem to work.

curl -F c=@image.png https://ptpb.pw Status: created, get UUID. Load paste in browser.

curl -X DELETE https://ptpb.pw/UUID Status: deleted

Paste still loads in browser, in different browser, and third party can also still load paste.

Hmm. Yeah, I reproduced this.

$ curl -X DELETE https://ptpb.pw/83f86795-e58d-4fba-a7aa-54c5a9d40851

So the deleted response means the paste was definitely deleted, and definitely doesn't exist anymore.

You'll also notice the Age: 51 header, which means you got a cached response instead of one from pb itself, also max-age=43200 which means varnish (and potentially any other foreign caching layers) will hold it for up to 43,200 seconds.

The current ptpb deployment was missing the cache invalidation configuration directive, VARNISH_BASE. I've added this to the deployment, and this works for me now.

Let me know if you disagree.
