Description
I have an Apache Airflow project and in that framework there's a massive use of dynamic module loading e.g. by manually creating modules from plugins and adding them to sys.modules.
I would like mypy to analyze my plugins but It cannot find those dynamic modules. One possible solution is to enable mypy plugins to provide a hook to resolve those imports the same way that is implemented in pylint: http://pylint.pycqa.org/projects/astroid/en/latest/extending.html#failed-import-hooks
Is there an easier way to achieve this?

Research direction
Start by reviewing mypy's plugin extension points and the failed-import hooks described in the linked astroid documentation. Determine whether an existing mechanism can support dynamically created modules; done would mean a decided, documented approach or an implemented plugin hook for resolving those imports.
