Run integrations test with remote-client

Add the ability to run the integration (ginkgo) suite using
the remote client.

Only the images_test.go file is run right now; all the rest are
isolated with a // +build !remotelinux.  As more content is
developed for the remote client, we can unblock the files and
just block single tests as needed.
