glusterd/ afr : set afr pending xattrs on replace brick
This patch is part one change to prevent data loss
in a replicate volume on doing a replace-brick commit
force operation.
Problem: After doing replace-brick commit force, there is a
chance that self heal happens from the replaced (sink) brick
rather than the source brick leading to data loss.
Solution: During the commit phase of replace brick, after old
brick is brought down, create a temporary mount and perform
setfattr operation (on virtual xattr) indicating AFR to mark
the replaced brick as sink.
As a part of this change replace-brick command is being changed
to use mgmt_v3 framework rather than op-state-machine framework.
Many thanks to Krishnan Parthasarathi for helping me out on this.
