[RFE]: set etcd snapshotRetention/cron

[shabazzfsher]

#Feature Request

Request description:
User cannot configure any of the ETCD section. So setting Cron Schedule or S3 configuration are both unavailable.

https://github.com/rancherfederal/rancher-cluster-templates/blob/main/charts/cluster-templates/templates/cluster.yaml#L81

Example:
Here is an example of what it should look like.

etcd:
  {{- if .Values.etcd.s3.endpoint }}
    s3:
      bucket: {{ .Values.etcd.s3.bucket }}
      {{- if .Values.etcd.s3.cloudCredentialName }}
      cloudCredentialName: "{{ .Values.etcd.s3.cloudCredentialName }}"
      {{- end }}
      endpoint: {{ .Values.etcd.s3.endpoint }}
      {{- if .Values.etcd.s3.endpointCA }}
      endpointCA: {{ .Values.etcd.s3.endpointCA }}
      {{- end }}
      {{- if .Values.etcd.s3.folder }}
      folder: {{ .Values.etcd.s3.folder }}
      {{- end }}
      region: {{ .Values.etcd.s3.region }}
  {{- end }}
    snapshotRetention: {{ .Values.etcd.snapshotRetention }}
    snapshotScheduleCron: {{ .Values.etcd.snapshotScheduleCron }}

The Rancher CRD supports these fields, they appear to just not be enabled yet in the helmchart.

We are working on this feature and functionality in the next release of rancher-cluster-templates. Thank you for your patience on getting this supported in the chart.
