ContainerSource CRD: metadata fields directly under "spec.template"

[antoineco]

Describe the bug

In the ContainerSource CRD, all ObjectMeta fields are nested directly under spec.template instead of spec.template.metadata. This prevents users from setting those fields in their Pod template.

eventing/config/core/resources/containersource.yaml

Lines 82 to 93 in abd3bdd

	template:
	description: 'Template describes the pods that will be created'
	type: object
	properties:
	annotations:
	description: 'Annotations is an unstructured key value map
	stored with a resource that may be set by external tools
	to store and retrieve arbitrary metadata. They are not
	queryable and should be preserved when modifying objects.
	More info: http://kubernetes.io/docs/user-guide/annotations'
