Support for topologySpreadConstraints on fluentd statefulset

[mattarmstrong]

Is your feature request related to a problem? Please describe.
podAffinity/podAntiAffinity is a performance/scalability concern (kubernetes/kubernetes#72479) and the community is shifting towards using pod topology spread as a replacement. The Karpenter autoscaler doesn't have support for podAffinity/podAntiAffinity at all, and recommends using topologySpreadConstraints.

Describe the solution you'd like
Support for configuring topologySpreadConstraints on the fluentd statefulset: https://github.com/SumoLogic/sumologic-kubernetes-collection/blob/main/deploy/helm/sumologic/templates/logs/fluentd/statefulset.yaml

Describe alternatives you've considered
Currently, I'm disabling podAntiAffinity completely in order to use Karpenter
