Allow to evacuate without specifying a target host
When the evacuate is run without specifying a target host, horizon sets an empty string for target host. But the evacuate api doesn't allow an empty string. As a result, nova returns "HTTP 400 Bad request". So this patch sets None as the target host when it isn't specified. Change-Id: Ia865a6c02e206fa49efc3095e8d3488f5638d0e3 Closes-Bug: 1793694
