Setting up the environment for devs

Setting up the environment for devs:

Front-end:

1. Remove "web client" code blocks from docker config files (all four docker yml files in the project's root directory)
2. In web_client's directory:
   rm node_modules
npm install rebuild
3. Rebuild docker and run:
   ./cjl build --no-cache
/cjl up -d
4. Run the front-end with:
   npm start while being in the web_service's directory

Now devs can work on front-end properly without touching the terminal.
Do not forget to NOT commit the *.yml files to the repository.
