[32/50] [abbrv] git commit: ifix CS-15609 Volumes can be created as a
part of VM creation when un-allocated space is insufficient on primary
storage
ifix CS-15609 Volumes can be created as a part of VM creation when
un-allocated space is insufficient on primary storage
check the availability of un-allocated primary storage space during
planning stage, for multiple-volume VM creation scenario
modification in StorageManagerImpl.java and StorageManager.java:
add a new method storagePoolHasEnoughSpace(List<Volumes>, StoragePool),
check if storagePool has enough space for all requested volumes
modification in FirstfitPlanner.findPotentialDeploymentResources:
handle multiple volume case, keep track of allocated volumes for pools
and call storagePoolHasEnoughSpace to check space availability
modification in AbstractStoragePoolAllocator.java:
extract capacity computation logic and make a new method in
StorageManagerImpl
