qapi: backup: add max-chunk and max-workers to x-perf struct
Add new parameters to configure future backup features. The patch doesn't introduce aio backup requests (so we actually have only one worker) neither requests larger than one cluster. Still, formally we satisfy these maximums anyway, so add the parameters now, to facilitate further patch which will really change backup job behavior.
