Kubernetes deployment failure due to ReadonlyRootFilesystem

[rafabene]

Problem

• carts-db (MongoDB)
• orders-db (MongoDB)
• rabbitmq
• user-db (MongoDB)

containers fail because their Root Filesystems are marked as readonly in the Kubernetes deployment file: https://github.com/microservices-demo/microservices-demo/blob/master/deploy/kubernetes/complete-demo.yaml

These containers should use readOnlyRootFilesystem: false.

I can provided a Pull Request if you agree with the solution.
