Add container images and deployments for Quickstarts

[marcduiker]

Describe the feature

Instead of building/running all the Quickstarts locally, we should also add container images and deployment files so they can be run quickly in Kubernetes (either locally or in the cloud). Creating images and running apps on Kubernetes is still a big learning curve for many developers so lets try to make it easier for them to run Dapr Quickstarts on K8s.

I suggest we start with one API (PubSub) for each of the languages in QS Pubsub to see if this works. When we have this initial set of images, other contributors can help out to build images for the other APIs.
