Is your feature request related to a problem? Please describe.
I've set up a cronjob/systemd timer to refresh blocklists periodically. Reloading these lists requires restarting the server, which potentially means downtime.

Describe the solution you'd like
Automatically reload blocklists using notify: https://docs.rs/notify/latest/notify/.

Describe alternatives you've considered
Restart the server each time a change to a blocklist file is updated.

Additional context
This could potentially extend to any part of the server configuration. Something like nginx -s reload or anything invoked with systemctl reload would be useful here.
