.Value is not cleared inside if condition for index

[aneeshkp]

After exported .Values is not cleared for index. Index is a sprig function not sure how to handle this.

• "{{ index .Values "etcd-operator" "cluster" "name" }}-client:2379"

To produce use either use zetcd helm charts or use following template
Template

{{- if .Values.etcd.operatorEnabled }}
            - "-endpoints"
            - "{{ index .Values "etcd-operator" "cluster" "name" }}-client:2379"
{{- else }}
            - "-endpoints"
            - "{{ .Values.etcd.endpoints }}"
{{- end }}

Expected :
{% if etcd.operatorEnabled %}
- "-endpoints"
- "{{ index "etcd-operator" "cluster" "name" }}-client:2379"
{% else %}
- "-endpoints"
- "{{ etcd.endpoints }}"
{% endif %}
Actual Result:
{% if etcd.operatorEnabled %}
- "-endpoints"
- "{{ index .Values "etcd-operator" "cluster" "name" }}-client:2379"
{% else %}
- "-endpoints"
- "{{ etcd.endpoints }}"
{% endif %}

[aneeshkp]

{{ index .Values "etcd-operator" "cluster" "name" }}
can be writen as {{ etcd-operator.cluster.name }}
But there are cases where the array is returned via a function
{{ index a func() }}

Indexing structures in Templates

If the data passed to the template is a map, slice, or array it can be indexed from the template. We use {{index x number}} where index is the keyword, x is the data and number is a integer for the index value. If we had {{index names 2}} it is equivalent to names[2]. We can add more integers to index deeper into data. {{index names 2 3 4}} is equivalent to names[2][3][4].
