Merge pull request #787 from anshul1886/CLOUDSTACK-8824-8825

CLOUDSTACK-8825, CLOUDSTACK-8824 : Fixed issues if vm.allocation.algorithm is set to firstfitleastconsumedFixed
following issues if vm.allocation.algorithm is set to firstfitleastconsumed

1. VM deployment failure if thre is only ZWPS in setup
2. VM migration is impossible from UI

To test

1. Create setup with ZWPS only
2. set vm.allocation.algorithm to firstfitleastconsumed in global settings
3. deploy virtual machine

observation: vm deployment will fail

After this fix it will pass

second scenario

1. Create Cloudstack Setup with two hosts (As it needs setup for migration)
2. Try migrating VM from UI

Observation: There will be error response in logs with nothing available in UI

After fix it will pass

Regarding BVT I am not sure whether there exists tests for firstfitleastconsumed vm allocation
algorithm.
