This is regarding our discussion in Slack. It felt like an easy, low hanging fruit, type thing to make possible real quick.

Could potentially use more test cases. However, locally I was able to utilize it like so:

# Existing behavior
./kubecfg show ./example.jsonnet
# ...
#
# Some remote file
./kubecfg show https://raw.githubusercontent.com/bitnami/kube-prod-runtime/master/manifests/components/nginx-ingress.jsonnet
# ...
# ...
# Apply some remote file
./kubecfg update https://raw.githubusercontent.com/bitnami/kube-prod-runtime/master/manifests/components/nginx-ingress.jsonnet
