allow disabling warnings for missing thresholds

[kaspar030]

I'm suddenly getting huge warnings for a missing threshold, e.g., here: kaspar030/laze#553 (comment)

I did specifically not set one up as github's workers are too inconsistent to provide meaningful results (I got too many false negatives).

Is there a way to disable the warnings?

@kaspar030 sorry you're running into this.

Would having a --no-thresholds flag or something be useful here?

In the mean time, you can create a threshold and then just clear the model right after you create it. This should get rid of the warning but not clutter up the results the same way that creating an extremely high/low threshold would.
