fix: Implements a custom K8s client to catch ApiErrors centrally

[Gmerold]

Description

This PR implements a custom K8s client to catch ApiErrors centrally.
The idea is to use a K8s client wrapped in a decorator handling ApiErrors. New k8s_client module implements a decorator and a Metaclass which is used to create a custom K8sClient and allows applying a decorator to every method of a base class (in this case a Lightkube Client).
