This also enabled a filesystem cache for the local docker compose setup, partially to be able to test this code but also to make it a bit more realistic in terms of its setup to production setups (though running a local blob storage means s3/azure blob performs much better then it does in real life)
Also renamed the controller serving the /blobs api from StorageController to BlobController which makes it more consistent with the compressed controller and with what the actual api is called.
