Description
Requirement: functionality that will reconfigure
a OBSERVER to become a voting member and vice versa.
Example of usage:
1. Maintain the Quorum size without changing the cluster size - in a 5
node cluster with 2 observers, I decide to decommission a voting
member. Then, I would like to configure one of my observers to be a
follower without any down time.
2. Added a new server to the cluster that has better resources than
one of the voting peers. Make the new node as voting peer and the old
one as observer.
3. Reduce the size of voting member for performance reasons.
Fix to ZOOKEEPER-107 might automatically give us this functionality.
It will be good to confirm that, and if needed, highlight work
that might be needed in addition to ZOOKEEPER-107.
