Warn on unknown fields

[thomasqueirozb]

A note for the community

Currently unknown fields are just completely ignored which might lead to client misconfiguration. Ideally we'll add #[serde(deny_unknown_fields)] in all config structs but this would likely break existing users. Before doing that we should start logging a warning to alert users that the field they're using does nothing and this will eventually stop working.

Implementation details

Possibly useful crate to implement this: https://crates.io/crates/serde-ignored-fields

Changes should be made to compiler.rs and/or to the configurable macro. Hopefully this is something that can be done without touching macro code
