KubernetesMockServer provides incomplete Configuration while creating test Config for KubernetesClient

[rohanKanojia]

Describe the bug

Kubernetes Mock Server initializes KubernetesClient with this opinionated Config during initialization

kubernetes-client/junit/kubernetes-server-mock/src/main/java/io/fabric8/kubernetes/client/server/mock/KubernetesMockServer.java

Lines 207 to 215 in 7074fbc

	protected Config initConfig() {
	return new ConfigBuilder(Config.empty())
	.withMasterUrl(url("/"))
	.withTrustCerts(true)
	.withTlsVersions(TlsVersion.TLS_1_2)
	.withNamespace("test")
	.withHttp2Disable(true)
	.build();
	}

However, we don't set important attributes like :

• Current Kubernetes Context being used
• Test username
• Test OAuthToken

This makes it difficult to use Kubernetes Mock Server with other clients (see #1601)

Fabric8 Kubernetes Client version

SNAPSHOT

Steps to reproduce

Create a test project and inspect kubernetesClient.getConfiguration() to see missing elements.

Expected behavior

KubernetesMockServer should create a valid opinionated Config so that it can be used by other clients.

Runtime

Kubernetes (vanilla)

Kubernetes API Server version
