Prepare the Serenata apps to be deployable in a Kubernetes cluster

[jvanz]

As the Serenata run in the same infrastructure used by the Querido Diario project we need to converge both projects to use the same underlying infrastructure. There is an ongoing process of migrating the Querido Diario workload to run on top of a Kubernetes cluster. So, we need to adapt the Serenata app to be deployable in the cluster as well.

The first step for this is to update the script to be able to build the container image and make it available in some registry.

@jvanz I also can't sign the issue for him until he makes a comment here on the thread. Github has this rule.
