Meet 'NoneType' issue when install helm chart with empty entry of manifest

[xho22]

When I'm installing istio chart by helm plugin, it returns 'NoneType' error. After debug, the cause if manifest of helm_status contains empty entry. And will run into issue from below:

cloudify-helm-plugin/helm_sdk/kubernetes.py

Line 125 in f37c74d

api_version = resource.get('apiVersion')

Chart manifest:

#Result of command: helm status istio-base -n istio-system -o yaml
config:
  defaultRevision: default

Coverted

The zzz_profile.yaml is empty. From my side, we don't suppose each key of manifest is present as some special chart design.

I found it's caused by a comment:
https://github.com/istio/istio/blob/1.22.4/manifests/zzz_profile.yaml#L39
I installed istio 1.22.3 and get the job done. However the issue is still should be fixed.
