Removed key generation, added apache web server

[danielepolencic]

The current Dockerfile is made of two parts:

• The first part uses composer to install the dependencies
• The second part creates the final Docker image with an Apache web server.

How you can try the changes:

docker build -t laravel-kubernetes-demo .

You can run the application with:

docker run -ti \
  -p 8080:80 \
  -e APP_KEY=base64:cUPmwHx4LXa4Z25HhzFiWCf7TlQmSqnt98pnuiHmzgY= \
  laravel-kubernetes-demo

And the application should be available on http://localhost:8080.

The container is generic and no APP_KEY was hardcoded.
