    Catch exception when use invalid architecture of image
    
    Currently, when attempting to rebuild an instance with an image with invalid
    architecture, the API raises a 500 error and leaves the instance stuck in
    the REBUILDING task state.This patch adds checking image's architecture
    before updating instance's task_state. And catches
    exception.InvalidArchitectureName then returns HTTPBadRequest.

Title:
  Instance is under rebuilding status always when use 'arm64'
  architecture image

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description
  ===========
  Got 'Unexpected API Error' when i use new image with property 'hw_architecture=arm64' to rebuild instance.
  And the status of instance stay 'REBUILD' always.

  Steps to reproduce
  ==================
  1. On x86 env, boot instance 'test'
  2. Set new image with  'hw_architecture=arm64'
  openstack image set --property hw_architecture=arm64 cirros-test
  3. Use the image to rebuild instance
  openstack server rebuild --image cirros-test test

  Expected result
  ===============
  Got badrequest, the status of instance rollback to active

  Actual result
  =============
  Got 'Unexpected API Error', the status of instance stay rebuild

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

      Zuul v3: use devstack-plugin-nfs-tempest-full

      ... and replace its legacy ancestor.
