cloudstack/test/integration/component/test_vpc_redundant.py
Wilder Rodrigues 094d29d7cd CLOUDSTACK-8915 - VRRP needs a cidr in order to work properly 
- The cidr was replaced by the single IP, which broke the feature.
   - Wait during transition from master to backup otherwise the test fails due to wronge state
