Description

Sometimes the container supports explicit reloads of the config. E.g. Caddy can do caddy reload --config /etc/caddy/Caddyfile

In this mode the container doesn't need to be restarted, it's enough to do sync+reload (not sync+restart).

Would be nice if there was a sync+reload mode where a custom reload command could be provided.

Not having to restart the container would mitigate issues like #12317
