Prometheus v5 data volume mismatch (no data persistence)

[Ilya Braude]

v5 of the catalog has the following config:

command:  ...  -storage.local.path=/prometheus ...
volumes:
 - /data/

So /data is being mounted as a volume, but all data is being stored in /prometheus, which means that Prometheus as it ships does not persist it's data!
