Refactor cds-mockserver helm chartjakartaistanbul

I did some changes to run that helm chart in integration tests using multicloud-k8s.
* I renamed helm/ directory into cds-mockserver/ based on "helm lint"
* I changed Deployment apiVersion to "apps/v1" due to "extensions/v1beta1" deprecation [1]
* I added "selector" into Deployment because it's required for "apps/v1" version [2]

Add missing .coafile, .yamllint and tox.ini files
