[sheepdog] [PATCH stable-0.8 1/2] sheep: reduce auto recovery log

[Hitoshi Mitake]

From: Saeki Masaki <saeki.masaki at po.ntts.co.jp>

Currently, auto recovery process produces one log message per one object.
The log messages consume too large disk space when a cluster has many
objects. This patch reduces the disk consumption by printing progress in a
style of percentage. The existing message is logged in debug level.
