Add new complexity rule for max imported names for a single module

Rule request

Thesis

Currently TooManyImportedNamesViolation only works on module level.

So, you can import up to 50 names from a single package! Like this:

from some import (
    name1,
    name2,
    ...
    name50,
)

And it won't be an issue.

This needs to be fixed. I suggest to add TooManyImportedModuleNamesViolation that will enforce to have less than 7? names per each module.

Good: import some and some.name1, some.name50
Bad: example above

This rule needs to be configurable.

Can I take it?

Do you suggest to add this check to ImportMembersVisitor or WrongImportVisitor ?

Assigned! Thanks a lot!
I guess ImportMembersVisitor suits better.
