Move to docker compose for deployment + Clean up branches

[karntrehan]

Description

The readme steps do not work for installing the repo. Grunt fails and many other dependencies fail.
We should add support for docker deployment to the repo.
We should also follow trunk based development with main, develop and feature branches. All projects should fork the main repo instead of creating branches inside this repo. Currently default branch is not main. This should be fixed.

[karntrehan]

Main branch's docker compose should contain only the building block. We should create a demo branch to contain gitpod information or package this into a "sample" / "demo" folder in the main branch.
