There are two reasons we may want NOT to use caching of pip deps:
1. When building a container, unless we specifically clean it up, it'll remain, even when we squash the image layers later.
2. When building a container, that cache is not useful, as we squash our containers later (so that layer is not cached really). And our CI cleans up the layers repo anyway.
3. Caching sometimes isn't great, and doesn't ensure we pick up the exact version (or latest) that we wish to...
This PR changes two locations in Scylla, both of which (also) build containers, so certainly relevant for 1, 2 above and possibly 3.
No real need to backport.
