Update chart to use stable Kubernetes APIs

Update the MAAS chart to use non-deprecated APIs [0], specifically
addressing the following resource types:
* ClusterRole
* ClusterRoleBinding
* Ingress
* Role
* Rolebinding

The APIs being migrated to are available in v1.19 or earlier. As of this
change, v1.19 is the oldest supported Kubernetes version, slated for EOL
on 2021-10-28. [1]

Also includes an HTK uplift that includes updated Ingress templates. [2]
