  sheep: avoid diskfull caused by recovery process

sheep can corrupt its cluster by diskfull with recovery process. For
avoiding this problem, this patch adds a new option -F to sheep. If
this command is passed to the sheep process, every sheep process of
the cluster skips recovery if there is a possibility of diskfull
during recovery.
