If people feel this strongly about the name of the "nova 
host-evacuate-live" CLI, they should propose changes to rename it (or 
deprecate it if it's dangerous and shouldn't exist).

How about deprecating "nova host-evacuate-live" and just add a --batch 
option to the existing "nova live-migration" CLI if people want to 
retain the functionality but hate the other name.
