When NewK8sClient() detects and error, it used to call FatalLogMsg() which causes a panic. There are additional features that can be used on Kubernetes clusters, but these are not a requirement for most functionalities of the driver. Instead of causing a panic, returning an error should suffice. This allows using the driver on non-Kubernetes clusters again. Fixes: #2452 Signed-off-by: Niels de Vos <ndevos@redhat.com>
