SAMZA-1334: fix pre-condition for ContainerAllocator to work properly We have observed issues when the LocalityManager reports the container locality mapping while the host-affinity is disabled in ContainerAllocator, in which the ContainerAllocator failed to release extra containers. Hence, fix is in the form of make sure the pre-condition is met for the ContainerAllocator w/o host-affinity: the localityMap from the JobModel should contain no preferred host info.
