FR: diagnostic: Allow to disable diagnostic with comments

[ufechner7]

pylint has the following options to disable warnings: https://pylint.readthedocs.io/en/latest/user_guide/messages/message_control.html

I like in particular the possibility to disable a warning in a specific line or block, using a special comment like

# pylint: disable-next=unbalanced-tuple-unpacking

I would like to have a special comment that works like this:

# jetls: disable-next=undef-global-var

This is a warning I get due to the buggy Base.@kwdef macro, so I would like to be able to disable it, but not globally, just for a specific line of code.

For context, an in-depth discussion of why@kwdef results in this warning can be found in #328 and #412.
