[sheepdog] [PATCH 0/3] use hash for vdi check and object recovery

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

On our environment, 'collie vdi check' of a 500 GB volume takes more than 10
hours with the current master, and this series makes it about 6 times faster.

I'd like to know how much faster other users would get with this feature.  Any
feedback would be appreciated.

  sheep: add operation to get object sha1 digest
  collie: use hash for collie check
  sheep: recover from local when target node has same content
