Having two different verbs allows the client to play with the frequency
of polling. Last word I've heard was that getAllVmStats is too heavy to
be called in the frequency that getMigrationStatuses is needed.

If Engine is happy to lock the frequency of getMigrationStatuses to that
of getAllVmStats, we can include migrateStatus within getAllVmStats. I
already conceded to this earlier in this thread.
