Unable to create cnf using kubernetes VIM

[Hiep Mai]

Currently, VIM Kubernetes uses ExtensionsV1beta1Deployment API [1], which is deprecated in version 1.16 [2], to deploy "Deployment" in Kubernetes so it's not possible to deploy a CNF using tacker.

    Use API apps/v1 to create deployment

    In Kubernetes version 1.16, deployment in ExtensionsV1beta1Deployment
    is deprecated [1], so it is unable to create cnf.
    In this patch, I first create method to get AppsV1Api [2],
    then I include app_v1_api_client in Kubernetes translate_template to
    create deployment.
