KubernetesMockServer does not return same List type as Kubernetes Api Server

Describe the bug

Related to https://github.com/fabric8io/kubernetes-client/issues/1601

This issue applies to scenarios when you're using Kubernetes Mock Server with clients other than Fabric8 Kubernetes Client.

When you use KubernetesMockServer in crud mode to get response of list() query operations, you'd get response like this:

{"apiVersion":"v1","kind":"List", "items": [{"kind":"Secret","apiVersion":"v1","metadata":{"name":"sh.helm.release.v1.test-project.v1",

However, with a real Kubernetes API server, we get a concrete List type

{"kind":"SecretList","apiVersion":"v1","metadata":{"resourceVersion":"225"},"items":[{"metadata":{"name":"sh.helm.release.v1.test-project.v1","namespace":"default","uid":"eeccb069-92c8-4220-9ec7-e2237d4ab660",

This is coming from here: https://github.com/fabric8io/kubernetes-client/blob/6c24a98a81a2acc905c2c8626326e603865e3131/junit/kubernetes-server-mock/src/main/java/io/fabric8/kubernetes/client/server/mock/KubernetesResponseComposer.java#L30-L32

This will work for KubernetesClient, however with other clients it causes problems in parsing list-objects.

Fabric8 Kubernetes Client version

SNAPSHOT

Steps to reproduce

Set up Kubernetes Mock Server with some other client and try doing list request, it would fail

Expected behavior

Kubernetes Mock Server list response should be same as Kubernetes Api Server

Runtime
