Adding External display manual tests to temp location in repo.

BUG=None
TEST=N/A

This is part of adding all test plans to the repo for easier
collaboration and maintenance. Currently this is being prototyped
by the display team alone. As process is smoothed out, will move
to a more permanent location and update documents.
