Please add support for (anti)affinity for all deployments, etc

[lhriley]

Summary

Please include the option to define pod placement using affinity:
https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity

Use cases

We have specific node pools dedicated to different resource requirements, and we place our pods using node / pod affinity. This is much more flexible than using nodeSelector for our purposes.

Proposed solution

Change these (and any I missed):

connect-helm-charts/charts/connect/templates/operator-deployment.yaml

Lines 35 to 40 in 54faa0c

	{{- with .Values.operator.nodeSelector }}
	nodeSelector:
	{{ toYaml . | indent 8 }}
	{{- end }}
	tolerations:
	{{ toYaml .Values.operator.tolerations | indent 8 }}

connect-helm-charts/charts/connect/templates/connect-deployment.yaml

Lines 35 to 38 in 54faa0c

	{{- with .Values.connect.nodeSelector }}
	nodeSelector:
	{{ toYaml . | indent 8 }}
	{{- end }}

to:

      {{- with .Values.<deployment>.nodeSelector }}
      nodeSelector:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- with .Values.<deployment>.affinity }}
      affinity:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- with .Values.<deployment>.tolerations }}
      tolerations:
        {{- toYaml . | nindent 8 }}
      {{- end }}

Is there a workaround to accomplish this today?

Hi there, I logged this internally to implement this. However, I can't give a timeline for when this can be completed. Please feel free to make a PR for this if you wish :)
