Update admin ui build pipeline

Description

To goal of this task is to update the tools and libraries used by the admin ui build pipeline to the newest versions available.

Exception: I've chosen the most recent Node 8.9.4 with long term support over the most recent available Node 9.4.0 to avoid the need to recompile modules that come with native dependencies.
