fix: warn on custom cache, add option for possibleTypes

[robertkowalski]

when using a custom cache in the render, memory would grow very fast.

run:

yarn
rm -rf node_modules/.cache/ && yarn build -p
clinic doctor -- node ./node_modules/.bin/hops serve

and in a seperate window a few times:

autocannon -c 50 http://localhost:8080/jobs/test

---

current users are now warned when they pass in a custom cache instance and we are offering an option to pass in possibleTypes via options.

in hops 16, we can remove custom caches.
