KubernetesMockServer should allow overriding its default /version expectation

[joshiste]

Is your enhancement related to a problem? Please describe

I want to override the VersionInfo returned by the io.fabric8.kubernetes.client.server.mock.KubernetesServer.

Describe the solution you'd like

Some easy way to specify the version the mock shall return

Describe alternatives you've considered

this.server.expect().get().withPath("/version")
                .andReturn(200, new VersionInfo.Builder().withMajor("1").withMinor("18+").build())
                .always();

This doesn't work for me as the expectation from KubernetesMockServer#onStart() is returned

Additional context

introduced with #3562

[joshiste]

Currently using this as workaround:

KubernetesMockServer mock = this.server.getKubernetesMockServer();
mock.clearExpectations();
mock.expect().get().withPath("/").andReturn(200, new RootPathsBuilder().addToPaths(mock.getRootPaths()).build()).always();
mock.expect().get().withPath("/version")
    .andReturn(200, new VersionInfo.Builder().withMajor("1").withMinor("18+").build())
    .always();

Hi @joshiste
The default version expectation provisioning was added as a feature in #3562 (#3536).

Your approach is the recommended ATM. However, we left the door open for future improvements.

One of the alternatives would be to expose the VersionInfo field:

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

Line 44 in 258f49a

private final VersionInfo versionInfo;

However, I'm not convinced about this approach.

Feedback is welcome ;)
