Bug description:
  [Impact]

   * Instances in error state cannot be evacuated.

  [Test Case]

   * nova evacuate <error_state_instance> <another_compute_host>
   * nova refuses to evacuate the instance because of its state

  [Regression Potential]

   * None
   * Passed tempest smoke tests locally.

  Note: one simple way to put an instance into error state is to
  directly change its database record, for example "update instances set
  vm_state='error' where uuid='XXXXXXXX'"


  We currently allow reboot/rebuild/rescue for an instance in the Error
  state if the instance has successfully booted at least once.

  We should allow "evacuate" as well, since it is essentially a
  "rebuild" on a different compute node.

  This would be useful in a number of cases, in particular if an initial
  evacuation attempt fails (putting the instance into the Error state).
