Autocompletion doesn't function with nested namespace packages

[xgalaxy]

Environment data

VS Code version:
Code 1.18.1 (929bacba01ef658b873545e26034d1a8067445e9, 2017-11-16T18:23:26.125Z)

Python Extension version:
0.8.0

Python Version:
Python 2.7.14 :: Anaconda, Inc.

OS and version:
Darwin x64 16.7.0

Actual behavior

The python vs-code extension does not properly follow nested namespaces for autocompletion. There is a similar problem with pylint documented here: pylint-dev/pylint#1686

Switching from pylint to flake8 removes the linting errors but autocomplete still does not function. Any of the google.cloud* packages exhibit the inability to get autocomplete information.

Expected behavior

Autocompletion of the google.cloud.* packages is desirable.
