The option can be used as a replacement of 'host' option
when several (sub)domains are needed to be registered for the module.
Note that you cannot combine both 'host' and 'hosts' in the config
because 'host' option is of a higher priority. Example:
mod_pubsub:
...
hosts:
- "pubsub1.@HOST@"
- "pubsub2.@HOST@"
