qemu-img: add compression option to rebase subcommand
If we rebase an image whose backing file has compressed clusters, we might end up wasting disk space since the copied clusters are now uncompressed. In order to have better control over this, let's add "--compress" option to the "qemu-img rebase" command. Note that this option affects only the clusters which are actually being copied from the original backing file. The clusters which were uncompressed in the target image will remain so.
