This adds a check for the existence of a (non-empty)
KUBECACHEDIR
environment variable that will be used to construct the cache directory path if present.Tested locally with variable set/unset and directory empty/non-empty, works fine.
Programmatic tests aren't there yet, I'd love a pointer on how you'd want to harness testing depending on an environment variable, since I only see usage of tests for e.g.
$KUBECONFIG
inacceptance_test
/integration_test
