- Changed the default kubeconfig loading to utilize the client-go's loader strategy. This allows users to use the Ark client without having to explicitly define a KUBECONFIG env var or argument. This more closely resemebles how Kubectl works and users are probably more used to while preserving the current rules. Signed-off-by: Justin Nauman <justin.r.nauman@gmail.com>
