Enhancement deploymentMetricsAggregator for Topologyspreadconstraint

[heyosi]

What would you like to be added: I would like to add Topologyspreadconstraint to deployment of /splunk-kubernetes-metrics/templates

topologySpreadConstraints:
- maxSkew: 1
  topologyKey: topology.kubernetes.io/zone
  whenUnsatisfiable: DoNotSchedule
  labelSelector:
    matchExpressions:
    - key: app
      operator: In
      values:
      - {{ template "splunk-kubernetes-metrics.name" . }}

Why is this needed: You can use topology spread constraints to control how Pods are spread across your cluster among failure-domains such as regions, zones, nodes, and other user-defined topology domains. This can help to achieve high availability as well as efficient resource utilization.
