Trigger on load events in addition to tagging

[awh]

We copy images from the host into a minikube VM using a command like this: docker save ... | ($(minikube docker-env) && docker load) - it would be handy if freshpod spotted tag contents being updated via this route also.

I'm trying to see if this is actually a common practice or not. I tend to assume most people don't do docker save+docker load multiple times to iterate on source code.

Is there a reason why you directly don't build it onto minikube's docker engine with docker build?
