Use local registry for app images

Browse Source 
Allow applications to be deployed without needing to set up a repository
in a remote Docker registry.

If the registry server starts with `localhost`, Kamal will start a local
docker registry on that port and push the app image to it.

Then when pulling the image onto the servers, we use net-ssh to forward
the that port from the app server to the deployment server.

This will allow the deployment server to pull the image from the
registry as if it were local, meaning we don't need to set up a cert.
