Description

It looks like un-subscription functionality is not working as expected.

Scenario:
1. Deploy a cartridge.
2. Subscribe to it.
3. Wait until an instance is activated.
4. Execute Un-subscribe option.
5. Now the running instances are terminated, but after some time new instances are spawned to replace the missing ones.
