A backup replica should be switch off after quorum of INSTANCE_CHANGE messages on backup instance.
- A strategy done in
INDY-1682should result in sending a special INSTANCE_CHANGE about instance change on backup instance X
- Once node got a quorum (n-f) of instance changes on backup instance X, it switches off the replica (
- add tests to check correct replica switch off
- testing perfomance changes (shouldn't be worse then in task
