cosmos-operator should be able to use private images

[danbryan]

cosmos-operator should allow the specification of imagePullSecrets when pulling an image.

I am doing a dive into this, and I found this in the config sample:

cosmos-operator/config/samples/cosmos_v1_cosmosfullnode_full.yaml

Lines 80 to 82 in d0ee04b

	imagePullSecrets:
	- name: name-of-kube-secret
	nodeSelector:

cosmos-operator/internal/fullnode/pod_builder.go

Lines 516 to 533 in d0ee04b

	func podPatch(crd *cosmosv1.CosmosFullNode) *corev1.Pod {
	tpl := crd.Spec.PodTemplate
	// For fields with sliceOrDefault if you pass nil, the field is deleted.
	spec := corev1.PodSpec{
	Affinity: tpl.Affinity,
	Containers: sliceOrDefault(tpl.Containers, []corev1.Container{}),
	ImagePullSecrets: sliceOrDefault(tpl.ImagePullSecrets, []corev1.LocalObjectReference{}),
	InitContainers: sliceOrDefault(tpl.InitContainers, []corev1.Container{}),
	NodeSelector: tpl.NodeSelector,
	Priority: tpl.Priority,
	PriorityClassName: tpl.PriorityClassName,
	TerminationGracePeriodSeconds: valOrDefault(tpl.TerminationGracePeriodSeconds, ptr(int64(30))),
	Tolerations: sliceOrDefault(tpl.Tolerations, []corev1.Toleration{}),
	Volumes: sliceOrDefault(tpl.Volumes, []corev1.Volume{}),
	}
	return &corev1.Pod{Spec: spec}
	}

It may already be supported, I will try some tests on this to see if it is
