-------------------------------------
Yes, I agree with you that we shall address 1) progress reporting and 2)
secondary master take over through separate JIRA's.
Let me know if you have any comments. The changes are same except new additions
to address the 1730 merge.

> intervention (i.e with out enable/disable and bulk assign/unassign) through
