Deploy Layotto on Kubernetes

[seeflood]

What would you like to be added:
Dapr has an easy-to-use solution to deploy it on Kubernetes,and we also need a solution for Layotto.
In order to implement it,maybe we need these things:

• a Dockerfile and image,see Layotto Dockerfile #178
• yaml file
• demo and document
• coding to make it easy to integrate with k8s? I'm not sure if it is needed.

Why is this needed:
Currently our demos only show users how to deploy Layotto binary files,but in production environment users need to deploy Layotto on K8S.
