I agree, it does more sense in the proxmox-rest-server crate.

Yeah, we can do that, we will just have to return the `syslog::BasicLogger`
and call `log::set_boxed_logger(..)` in the api/proxy `run()` function.

Should we also return the max_log_level somehow, maybe in a tupel?
Currently I am already setting it in the `init_syslog_logger` function
using log::set_max_loglevel(..)`.
