Remap diagnostic error level

[mosheavni]

Hi, I have flake8 for diagnostics, and it marks the error line too long as error. I'd rather it be on informational level. I tried:

  "python.analysis.information": ["line too long"],

But of course it does not work. Can it be done? Also, when fixing a problem, the gutter doesn't refresh until I save the file. Can I make it lint as soon as I make the fix? Thanks.
