NGINX+PHP7+MySQL+Node.js environment

1. Set root in nginx.vhost
2. Set necessary ports in web container in docker-compose
3. Change a php version, a list of required packages and extensions in php.dockerfile if needed.
4. Modify php.ini file if needed. It will be injected into the container.
5. Set necessary ports, env variables in mysql container in docker-compose. All data is persistant. You can access DB through mysql host (using the container name) in the app.
6. By default in vue container you will have vue-cli installed and npm run dev executed. Initially you need to install all required dependencies.
7. Set necessary ports, env variables in vue container in docker-compose. /usr/src/app dir is created in vue container, so set a volume with the app to the dir.
