Since placement service was introduced, there have been several conditions where instances are not well distributed among multiple compute nodes. For example with the default configurations if a user creates multiple instances concurrently, these instances might be packed into a single compute node because placement returns the same results until any instance is actually launched at compute nodes. This change introdices two tunable parameters about nova-scheduler so that we can implement better distribution of nova instances in some usecases.
