I am trying to limit max subscriptions per user, l could find 'zone.external.max_subscriptions' in the emqx.conf file, however I cant figure out whether this is for a particular user or for all the users. How can I do it for user or mountpoint basis? Can I configure this parameter for a particular mountpoint or user? And how?

## Maximum number of subscriptions allowed, 0 means no limit.
## Value: Number
zone.external.max_subscriptions = 100

It only limits max count topics per user on the specified zone (i.g: external).

After reviewing codes, it not works on the current version (3.2.3). I'll try to fix it later
