Incompatible templates for Kubernetes >= 1.16

[Sparika]

Summary:

Since Kubernetes 1.16, some API have been deprectated as can be seen here.

DaemonSet, Deployment, StatefulSet, and ReplicaSet resources will no longer be served from extensions/v1beta1, apps/v1beta1, or apps/v1beta2 by default in v1.16. Migrate to the apps/v1 API

Deployment of Skydive on Kubernetes 1.16 using helm fails with an error

helm install skydive-helm
Error: validation failed: [unable to recognize "": no matches for kind "DaemonSet" in version "extensions/v1beta1", unable to recognize "": no matches for kind "Deployment" in version "extensions/v1beta1"]

Similar to error reported here.

Expected change
For both agent and analyzer, the api version should be changed:

apiVersion: apps/v1
kind: DaemonSet

apiVersion: apps/v1
kind: Deployment

And the following should be added to both files:

spec:
  selector:
    matchLabels:
      app: {{ template "fullname" . }}
