Ability to deny all warnings

[Nemo157]

Is your feature request related to a problem? Please describe.
I want to easily deny all the things that cargo-deny considers as a warning by default in my CI jobs.

Describe the solution you'd like
Something similar to cargo check --deny=warnings. Because there's not a general purpose --deny flag this could maybe just be cargo deny check --deny-warnings.

Describe alternatives you've considered
Copy-pasting a base deny.toml into all my crates, or somehow merging it into any local config from a CI job
