[sheepdog] [PATCH v2 0/3] simplify join process

[MORITA Kazutaka]

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

v2:
 - fix style problems
 - replace nr_members with nr_nodes
 - explain that 'nodes' doesn't contain 'joining' in sd_check_join_cb
 - fix unit test

This is the first series to refactor sheep/group.c and the cluster
drivers.  This simplifies the current join process a lot and will
improve code readability.  The other changes like removing a master
will be sent after this series is merged.

The first two patches prepare for the third one.

MORITA Kazutaka (3):
  sheep: split cluster_info into system_info and cluster_info
  sheep: access config entries with one function call
  sheep: start cluster if all the nodes in the previous epoch are
    gathered
