Title:
  Live migration fails using "openstack server migrate"

Status in python-openstackclient:
  New

Bug description:
  Description
  ===========

  Attempting to migrate a server using the "openstack server migrate"
  command fails if the server lives on shared storage (like Ceph).

  The problem is that nova/compute/api.py:live_migrate() expects a
  "block_migration" boolean whereas
  openstackclient/compute/v2/server.py:take_action() passes a
  "shared_migration" boolean.

  Steps to reproduce
  ==================

  Ensure instance in on shared storage and attempt to migrate it:

  [root@phsospc2n2 ~]# openstack server migrate --live phsospc2n5
  --shared-migration --wait testlm

  Expected result
  ===============

  [root@phsospc2n2 ~]# openstack server migrate --live phsospc2n5 --shared-migration --wait testlm
  Complete

  Actual result
  =============

  [root@phsospc2n2 ~]# openstack server migrate --live phsospc2n5 --shared-migration --wait testlm
  phsospc2n4 is not on local storage: Block migration can not be used with shared storage. (HTTP 400) (Request-ID: req-7d535333-4220-457b-af81-0b90290bf84d)

  
  Environment
  ===========

  python-openstackclient-2.2.0-1.el7.noarch
