panlint: implement #nolint pragma

[wdpypere]

As I started using panlint to cleanup our tree I found it fails for ssh authorized keys on line too long.
Now I could not find a way to exclude them, or split them in a functional way to keep panlint happy as well as maintain the expected output in the profile.

We encounter the same problem and simply ignore the errors for those files, do you have a better idea for how to handle this?

[wdpypere]

well, we run panlint as a test on changes so having a --exclude option or something and then a regex for something like "ssh-rsa " ?

[wdpypere]

We now load the ssh keys in a different way, so this is no longer an issue for us. afaik, this can be closed.

We've had this problem with a couple of other lines where we are embedding content. How about a generic #nolint pragma to tell panlint to ignore the following lines?

[gombasg]

Yup, I've seen panlint complaining path literals should not have trailing slashes - except those strings were not Pan path literals.

No static analyzers can ever be perfect, so having a way for suppressing certain warnings is necessary.

Could you take a look at #220? The rest of the changes that follow the re-factoring work there provide such functionality.

[ned21]

@jrha I am happy with #220 but it depends on #219 where I hadn't reviewed the regexes in detail to be confident of merging it. And now we have #222 which will probably invalidate both of them. In which order do we proceed?

It's not that much work to redo #222 on top of the other two if that helps.
