Make frontend build in Docker image optional (getredash#4879)

* Add build arg to Dockerfile to control if we should build frontend assets

* Move more env settings into the shared one.

* Use build arg in docker-compose to skip frontend build.

* CirlceCI: Skip building frontend assets in backend tests

* Create dummy template files

* Expand file names manually.

* Add build arg to skip dev dependencies.

* Update Dockerfile

* Reverse logic of skip_dev_deps to what it should be.
