See if log level can be configured on a per-service level

[RobertZ2011]

Would be a nice feature and would help cut down on irrelevant messages when you're trying to debug a specific issue.

I think this can be done with https://defmt.ferrous-systems.com/filtering#defmt_log already?

The DEFMT_LOG environment variable supports this. Specifically, a module path can be used in the filter. I don't think there's anything to do on our part to add "more" support for this.
