* Add frontend for the Tensorboard Web-app
This commit contains the code for the frontend of the Tensorboard
web-app. It completes the GSoC 2020 project for building the
standalone TWA for Kubeflow.
The app is not yet fully integrated to the Kubeflow dashboard, so
the README.md file contains documentation on how to build, run and
use the web-app locally.
Also, a Dockerfile was added in order to build a playground image
of the web-app. The 'deploy' folder contains manifests that will
enable the TWA to properlly run on the cluster in the future.
* Update README.md
