V2:
1. Redesign the secondary qemu(use image-fleecing)
2. Use Error objects to return error message
3. Address the comments from Max Reitz and Eric Blake

Add new block driver interfaces to control block replication
quorum: implement block driver interfaces for block replication
NBD client: implement block driver interfaces for block replication
allow writing to the backing file
Allow creating backup jobs when opening BDS
