Charts: [stable/spinnaker] unable to install stable/spinnaker

[musabmasood]

Describe the bug
Simply installing the latest spinnaker helm chart is failing (helm chart version 1.11.1):

helm install --name ss --namespace ss stable/spinnaker

Error:

Error: parse error in "spinnaker/templates/configmap/service-settings.yaml": template: spinnaker/templates/configmap/service-settings.yaml:37: function "mergeOverwrite" not defined

Version of Helm and Kubernetes:

Helm version:

Client: &version.Version{SemVer:"v2.12.3", GitCommit:"eecf22f77df5f65c823aacd2dbd30ae6c65f186e", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.12.3", GitCommit:"eecf22f77df5f65c823aacd2dbd30ae6c65f186e", GitTreeState:"clean"}

Kubernetes version: 1.12

Which chart:

stable/spinnaker

Oh, it seems that mergeOverwrite function is available only since helm 2.13.0
Please try upgrading to the latest Helm 2.* , if you can.

We might need to replace mergeOverwrite logic with reversed merge in order to keep a backward compatibility of stable/spinnaker with older Helm versions.
