This is a good point.

Personally I'd prefer to see it go the other way and convert everything to the 
"recreate" terminology, including the external API.

 From the CLI perspective, it makes no sense that "nova evacuate" operates after 
a host is already down, but "nova evacuate-live" operates on a running host.
