test: Implement snapshot create/delete/revert APIs
Again stolen from qemu_driver.c, but dropping all the unneeded bits. This aims to copy all the current qemu validation checks since that's the most commonly used real driver, but some of the checks are completely artificial in the test driver. This only supports creation of internal snapshots for initial simplicity.
