METRON-2256 NodeJS Module puppeteer moved to be a dev dependency.

[tigerquoll]

The puppeteer module is used for GUI testing, and allows Chrome to be driven headless for GUI testing purposes. Every time that puppeteer is installed, (which is every build), it downloads Chrome (80-120 MB download, 250+ MB on disk). Puppeteer cannot be configured to cache the download for future use.

Angular/NodeJS has a concept a dev dependency, which is only installed for testing. Dev-dependencies are not installed during a full dev build/deployment. Moving puppeteer to be a dev-dependency means that Chrome is only downloaded when automated testing is about to happen.

This patch works against Master before Metron-2243 was merged on 3rd September. Past that date, an issue that prevents automated GUI tests from completely correctly was inadvertently introduced, and thus automated GUI testing cannot confirm correct operation.

Once this issue has been identified this PR will be updated to Merge with the current Master branch.
