* Update plugins/replication from branch 'master'
to 9c21a2f5cc539b5a13d2646edc15bd17d7977fb3
- Merge "Avoid starting tasks which are not present under waiting storage area"
- Avoid starting tasks which are not present under waiting storage area
This change only starts the replication tasks which are present
under the ../waiting directory and ignores any extra refs which
it was orginally intended to push. This will reduce the duplicate
work because the absence of tasks under ../waiting directory
implies that it has already been started/completed by other
nodes.
