Cleanup Dockerfile.

* make .dockerignore `ncdu -X` compatible to easily inspect build context
* remove cargo-chef as it was introducing more problems than it was solving
* remove rocksdb packages
* add ca-certs in the resulting image. We need that to be able to make https
  connections from container with proxy to the console.
