[sheepdog] [PATCH v3 0/2] provide recovery progress information to users

[Hitoshi Mitake]

Current sheepdog doesn't have a capability of showing progress of
recovery process. This patchset implements the feature. After applying
this set, users can see the progress like this:

$ sudo collie node recovery --progress
 99.7 % [==============================================>] 7047 / 7068

v3:
 - clean coding style
 - make struct recovery_state a general mechanism for getting recovery
   status. Ordinal "collie node recovery" uses struct recovery_state
   for detecting recovery state instead of a result of request.

v2:
 - make this feature as an option of "node recovery", not a new subcommand
 - clean coding style, especially in collie side
 - don't use new variables for indicating the progress in sheep side

Hitoshi Mitake (2):
  sheep: enhance STAT_RECOVERY for prividing information of recovery
    state
  collie: add a new option --progress to "node recovery" for showing
    recovery progress
