Unable to create a Template on OCP3

[mchoma]

This is clone of xtf-cz/xtf#373 because I believe kubernetes client should keep backward compatibility.

I am getting

io.fabric8.kubernetes.client.KubernetesClientException: Failure executing: POST at: https://api.multinode-nfs-022.dynamic.xpaas:8443/apis/template.openshift.io/v1/namespaces/istraka-namespace-2/templates. Message: the API version in the data (v1) does not match the expected API version (template.openshift.io/v1). Received status: Status(apiVersion=v1, code=400, details=null, kind=Status, message=the API version in the data (v1) does not match the expected API version (template.openshift.io/v1), metadata=ListMeta(_continue=null, remainingItemCount=null, resourceVersion=null, selfLink=null, additionalProperties={}), reason=BadRequest, status=Failure, additionalProperties={}).

With 4.9.2 it was OK.

After some debugging, the difference is in URL:
4.9.2:

https://api.multinode-nfs-022.dynamic.xpaas:8443/oapi/v1/namespaces/istraka-namespace/templates

4.10.2

https://api.multinode-nfs-022.dynamic.xpaas:8443/apis/template.openshift.io/v1/namespaces/istraka-namespace-2/templates

Workaround:

template.setApiVersion("template.openshift.io/v1");

@rohanKanojia @gastaldi Can you have a look please? We have talk about something similar in #1805
