Doing a "docker pull" to check if an image exist on hub takes a long time for the number of images, in particular in the linuxkit/kernel-mainline repo. Instead, get a list of tags on Hub and check that way. This does not check if the image was signed, but should be good enough. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@docker.com>
