## Description
Following up on @webyneter attempt in #1205, which is now getting outdated, I've tried to make Gulp task runner work with Docker. There is no documentation yet, but this seems to work locally with the custom bootstrap compilation...
- [x] Add a node image for local developement
- [x] Proxy the django image rather than localhost in Browser sync, pass header to keep hostname
- [x] Don't call the runserver command from Gulp, let docker-compose handle
- [x] Update package.json & gulpfile.js templates to reduce the number of unwanted empty lines
- [x] Use [multi-stage build](https://docs.docker.com/develop/develop-images/multistage-build/) in production to make sure the static assets are produced
- [x] Update documentation
- [x] Verify that the previous issue with static assets missing from production isn't there
## Rationale
Currently, the static build isn't working nicely with Docker, extra manual setup is required.
Fixes#1762
* Add Bootstrap to package.json in case of custom_bootstrap_compilation
* Update JS task runners and base HTML to handle custom scss compilation
* Generate a vendors.js with custom bootstrap compilation + Gulp
* Update documentation accordingly
* Add missing if/endif in gulpfile
* Update to Bootstrap v4 final
* Introduce static asset build infrastructure
* Enhance gulpfile.js
* Introduce node service
* BrowserSync debug-only support
* Remove newline before BrowserSync debug-only support section
* FIx node Dockerfile package.json COPY
* Try fiixing node Dockerfile package.json COPY ones again
* Switch to `node:7-slim`
* Try switching to node:6
To account for possible node:7 docker-compose incompatibiltiy
* Revert "Try switching to node:6"
This reverts commit 62cc02df1a.
* Try switcging workdir to /app
* Try utilizing relative package.json path
* Resetting to the last version working locally with docker-compose 1.11.x
