Make add_kernel_initrd_annotations_to_yaml generic

[fidencio]

Some time ago @sprt added a function to set the kernel and initrd to the resource's yaml file, and this can be found at

kata-containers/tests/integration/kubernetes/setup.sh

Lines 47 to 80 in 6ead48e

	add_kernel_initrd_annotations_to_yaml() {
	local yaml_file="$1"
	local mariner_kernel_path="/usr/share/cloud-hypervisor/vmlinux.bin"
	local mariner_initrd_path="/opt/kata/share/kata-containers/kata-containers-initrd-mariner.img"
	local resource_kind="$(yq read ${yaml_file} kind)"
	case "${resource_kind}" in
	Pod)
	echo "Adding kernel and initrd annotations to ${resource_kind} from ${yaml_file}"
	yq write -i "${K8S_TEST_YAML}" 'metadata.annotations[io.katacontainers.config.hypervisor.kernel]' "${mariner_kernel_path}"
	yq write -i "${K8S_TEST_YAML}" 'metadata.annotations[io.katacontainers.config.hypervisor.initrd]' "${mariner_initrd_path}"
	;;
	Deployment|Job|ReplicationController)
	echo "Adding kernel and initrd annotations to ${resource_kind} from ${yaml_file}"
	yq write -i "${K8S_TEST_YAML}" 'spec.template.metadata.annotations[io.katacontainers.config.hypervisor.kernel]' "${mariner_kernel_path}"
	yq write -i "${K8S_TEST_YAML}" 'spec.template.metadata.annotations[io.katacontainers.config.hypervisor.initrd]' "${mariner_initrd_path}"
	;;
	List)
	echo "Issue #7765: adding kernel and initrd annotations to ${resource_kind} from ${yaml_file} is not implemented yet"
	;;
	ConfigMap|LimitRange|Namespace|PersistentVolume|PersistentVolumeClaim|RuntimeClass|Secret|Service)
	echo "Kernel and initrd annotations are not required for ${resource_kind} from ${yaml_file}"
	;;
	*)
	echo "k8s resource type ${resource_kind} from ${yaml_file} is not yet supported for kernel and initrd annotations testing"
	return 1
	;;
	esac
	}

This was very handy and very specific to the Azure LInux case, but we need to expand it to:

• rename the function to a generic name (add_annotations_to_yaml)
• receive the annotation name that it's going to set as a parameter
• receive the annotation value that it's going to set as a parameter

This will end up with two calls to

kata-containers/tests/integration/kubernetes/setup.sh

Line 87 in 6ead48e

add_kernel_initrd_annotations_to_yaml "${K8S_TEST_YAML}"

, one for setting the kernel and another one for setting the initrd, which is fine.
