Actions:
1. Update '/etc/nova/nova.conf' with long 'reclaim_instance_interval'

2. Create net and subnet;
3. Create and run two instances (vm1, vm2) inside same net;
4. Create a volume and attach it to an instance vm1;
5. Delete instance vm1 and check that it's in 'SOFT_DELETE' state;
6. Delete instance vm1 with 'force' option and check that it's not
present.
7. Check that volume is released now and has an Available state;
8. Attach the volume to vm2 instance to ensure that the volume's reuse
doesn't call any errors.
