Stephen Finucane 162f4769b8 Microversion 2.68: Remove 'forced' live migrations, evacuations 
Update the commands and Python API bindings to reflect the new
microversion. The various evacuate microversion functions are DRY'd up
along the way.

Change-Id: Ibfc905292258ffde05800387e5d6bbad4823085c
Signed-off-by: Stephen Finucane <sfinucan@redhat.com>
Depends-On: https://review.openstack.org/#/c/634600/
Implements: blueprint remove-force-flag-from-live-migrate-and-evacuate
