We need to make sure that our containers have a /cache_namespaces/acousticbrainz folder (as configured in config.py) and that it's writable by the web process.

Consider if this should be shared as a volume mount so that it persists as new versions of AB are deployed, or if it should be transient (if it's local to a container then we will lose the cache every time we redeploy AB and it'll have to be recomputed - this is not necessarily a bad thing)
