openstack overcloud status not working after Undercloud upgrade to Stein

[Jose Luis Franco]

After performing the upgrade of the Undercloud from Rocky to Stein followed by the "openstack overcloud upgrade prepare" one of the scripts executed the "openstack overcloud status" command, resulting in the following error:

(undercloud) [zuul@undercloud-5705 ~]$ openstack overcloud status
Exception occured while running the command
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/tripleoclient/command.py", line 32, in run
    super(Command, self).run(parsed_args)
  File "/usr/lib/python2.7/site-packages/osc_lib/command/command.py", line 41, in run
    return super(Command, self).run(parsed_args)
  File "/usr/lib/python2.7/site-packages/cliff/command.py", line 184, in run
    return_code = self.take_action(parsed_args) or 0
  File "/usr/lib/python2.7/site-packages/tripleoclient/v1/overcloud_deploy.py", line 1058, in take_action
    execution = payload['execution']
KeyError: 'execution'
'execution'

The error is consistent. When trying to run it manually it fails with the same error. Not sure if it happens in a fresh Stein deployment though.

Strangely, we cherry-picked https://review.opendev.org/#/q/I010ea5d732aba97a554e868f62a19e6fdaee8889 all the way to stable/queens without a bug, which breaks 'overcloud status' command:/

We've to backport https://review.opendev.org/#/c/664871/, which fixes the broken 'overcloud status' command on master and do stable branch python-tripleoclient releases or revert above mentioned backports.
