React Front-End UI

This commit is to move the React front end files from the Clamp Policy Repo to the Onap Gui Policy Repo.
Also created the added Maven featue to compile the React project via Node and NPM, and copy the production files to the target directory.

Fixed in gitignore that was ignoring the contents inside the logs/ directory.

Reformated JS spacing files from 4 spaces to 2 spaces.

Fixed Broken JEST test

Applied Jim's Code Review as well updated Node Version from 12.18 to 14.17 accross the modules.  Unfortunately cannot apply NPM version since it broke npm install.

Fixed ONAP Job Builder Linting Error

Applied Jim's Second Code Review
