[FR]: support mypy

[alexeagle]

What is the current behavior?

I adopted https://github.com/bazel-contrib/bazel-mypy-integration but haven't been doing much maintenance there.
Things get a lot simpler by using the linting mechanics from this repo, all we need is the mypy aspect.

Describe the feature

python/mypy#3912

@alexeagle I've created a separate repo for Bazel MyPy rules over here which is heavily inspired by bazel-mypy-integration but adds a few missing features, namely:

1. Support out of the box for protobuf/gRPC type stubs
2. PEP-561 support for stubs-only packages.

I reckon it'd be great to see these extra features integrated into rules_lint, and am happy to contribute if this is something others might find useful!

@alexeagle
How does this issue play together with this commit of yours saying "there will be no mypy support in rules_lint": 944f143

Is this Feature Request now rejected?

And if so, is there some agreement in the community where mypy for Bazel should be maintained?
https://github.com/bazel-contrib/bazel-mypy-integration is not in a good shape, but could be improved. Actually, I have a PR open there with some proposed fixes.

I am happy too contribute to another project, but right now I am confused which project is the best bet.

Hey @martis42 - I am waiting on an answer from @f0rmiga about where this can live, as it's funded by his company right now. I think likely options are rules_py - aspect-build/rules_py#235 or maybe get bazel-mypy-integration in better shape.
