Feature request: dict auto completion

[thernstig]

I was asked to re-create this ticket in Jedi when originally raising the request in pythonVSCode, please refer to: https://github.com/DonJayamanne/pythonVSCode/issues/1145

Environment data

VS Code version: 1.14.2
Python Extension version: 0.7.0 (3 August 2017)
Python Version: 3.6.1
OS and version: Windows 10 Home, Version 1703, OS-version 15063.483

Actual behavior

When pressing ctrl+space on a defined dict, no suggestions are shown for the keys in the dict.

Expected behavior

If I use a defined dict in my file I want it to suggest the keys to select automatically.

Here is an example of what I mean:
