Closes #17 .

• Dockerfile for the frontend
• Dockerfile for the cache service
• docker-compose.yml file to start the
• Redis Container
• keycloak server container
• frontend
• redis micro-service

In order to containerize the cache service I had to update the package since some dependencies were missing.
I recommend separating the project in two main folders frontend and backend, or cache-service and app whatever suits better!

I need help though. Seems like I cannot get the cache service to connect with redis. I tried a bunch of different configurations both on docker-compose and in the project itself. Can anyone help or have an ideia for this? I decided opening up the PR because I practically gave up after a few hours. The error is pretty straightforward, but I could build a configuration that makes the cache service "see" the redis.
