Use cached images for integration tests

Add alpine and busybox as the two seeded images that can
be put into the tests' storage without the need to pull
it over the network.  Add the following to the kpod_TEST.bats
file:

function setup() {
    copy_images
}

Also, export several image names for shorter reference:

* BB -> docker.io/library/busybox:latest
* BB_GLIBC -> docker.io/library/busybox:glibc
* ALPINE -> docker.io/library/alpine:latest
* FEDORA_MINIMAL -> registry.fedoraproject.org/fedora-minimal:latest

And finally, there were two pervasive changes I made in
tests:

* Because we use temporary storage, we do not need to rmi at the end of each test
* We no longer need to pull most images because they are added via copy_images
