Option to specify immutable classes

[finswimmer]

Hello,

my feature request was already mentioned here by @DylanYoung. Because the issue was about another topic, I thought it would be a good idea to put it into a new ticket.

I'd like to have an option to specify immutable classes. My concrete use case is fastapi. When you define your endpoints you have something like Depends() or Query() in the function calls, which results in a B008 error message by flake8-bugbear.

Of course one can mark those lines with a # noqa: B008, but depending on how large the application is, this is not quite.
