Update the Configuration logic for kubernetes v12.0.0

[collivier]

As highlighted by [1], kubernetes v12.0.0 and newer asks for the use of Configuration.get_default_copy() [2].

It detects if Configuration.get_default_copy() is defined to preserve the backward compatibility.

This patch is key for Functest as latest OpenStack upper-constraints ask for kubernetes 12.0.1. We do falsy override kubernetes to 11.0.0 to please xrally_kubernetes.

@prazumovsky @andreykurilin @jukosone I noted xrally_kubernetes leverages on the deprecated API too. diff --git a/xrally_kubernetes/service.py b/xrally_kubernetes/service.py index 5d60070..8108d03 100644 --- a/xrally_kubernetes/service.py +++ b/xrally_kubernetes/service.py @@ -16,11 +16,11 @@ import re
