[codecov] Only report a failure when the coverage decreases by more than 1%

Created by: muffato

Use case

I've always found it very annoying that codecov complains about meaningless decreases of the coverage, like 80.88% (-0.04%) compared to e2e90e5 . Coveralls has been configured to not report small differences but I couldn't find how to configure this in codecov ... until today :)

Description

Do not complain about small decreases of the coverage

Possible Drawbacks

Does anyone need such precision and fine-grain decision in the codecov report ?

Testing

Have you added/modified unit tests to test the changes?

N/A, but I have checked that the yaml file is valid with

curl --data-binary @.codecov.yml https://codecov.io/validate

Have you run the entire test suite and no regression was detected?
