 * If the service is missing, create it, import its properties, and import the
 * instances.  Since the service is brand new, it should be empty, and if we
 * run into any existing entities (SCF_ERROR_EXISTS), abort.
 *
 * If the service exists, we want to upgrade its properties and import the
 * instances.  Upgrade requires a last-import snapshot, though, which are
 * children of instances, so first we'll have to go through the instances
 * looking for a last-import snapshot.  If we don't find one then we'll just
 * override-import the service properties (but don't delete existing
 * properties: another service might have declared us as a dependent).  Before
 * we change anything, though, we want to take the previous snapshots.  We
 * also give lscf_instance_import() a leg up on taking last-import snapshots
 * by importing the manifest's service properties into a temporary service.
