Move Deployment API group from extensions/v1beta1 to apps/v1 (#1331)

In 1.9, kubernetes prompted Deployment to apps/v1 and finally deprecated
extensions/v1beta1 support in 1.16. Users will see the following error message
in log when fission components try to submit Deployment to the k8s API server
and specify extensions/v1beta1 as API group.

error: unable to recognize "deployment": no matches for kind "Deployment" in version "extensions/v1beta1"

This PR updates call to k8s API server and apiKind in chart files to avoid fission failure in 1.16.
