Deprecate list module specification in BadNameAttributeUseLinter

[mschwager]

Subclasses that implement BadNameAttributeUseLinter currently must specify:

{
    "object_attribute": [
        ["module_name1", "module_name2"],
        ["module_name3", "module_name4"],
    ]
}

To migrate toward our new "module path" concept we should use module path strings instead of lists, e.g.

{
    "object_attribute": [
        "module_name1.module_name2",
        "module_name3.module_name4",
    ]
}

This will make our interfaces take similar objects to specify similar concepts. E.g. specifying a fully-formed module as 'mod1.mod2.mod3.attr' instead of ['mod1', 'mod2', 'mod3', 'attr'].

This should also include ensuring that fully-formed module paths are being passed. This will probably require a Namespace to be passed in when comparing modules and attributes.
