  Seems the culprit is missing python-vitrageclient package, which is
  part of heat requirements.txt - but not installed as a dependency when
  installing heat-engine from UCA
  (https://github.com/openstack/kolla/blob/master/docker/heat/heat-
  engine/Dockerfile.j2)

  ==================================================================

  [Impact]

  heat depends on stevedore to load client entry points. In the past,
  stevedore would just give a warning if a client failed to load (ie. due
  to an uninstalled Suggests dependency). Then stevedore changed code
  to use importlib.metadata which no longer supports ep.load(require=False), and now the failure to load a client entry point will error hard along the lines of that described above (ModuleNotFoundError: No module named 'vitrageclient'). In other words, all openstack clients that heat depends on must be installed or heat will fail hard. By getting python-vitrageclient into Ubuntu main, we can move it from Suggests to Depends and it will always be installed for heat binary packages.

  [Testcase]

  Taken from: https://bugs.launchpad.net/bugs/1958988 (Thanks to
  Francois Michaut)

  Installing heat with the following commands :

  add-apt-repository cloud-archive:xena
  apt update
  apt-get install heat-api heat-api-cfn heat-engine

  will reproduce the issue.
  heat-engine service will crash and restart continuously, all heat-related commands will fail ("openstack stack list" will output (after a very long time): ERROR: Internal Error).

  In heat-engine logs, we can see that a module named "vitrageclient" is
  missing. Running "pip3 install python-vitrageclient" fixed the issue
  and heat started working correctly.

  ==================================================================

  [MIR] python3-vitrageclient

  [Availability]
  Currently in universe

  [Rationale]
  Heat is an OpenStack project that we're ready to support in main, and it has a hard dependency on python-vitrageclient.

  [Security]
  No security history

  [Quality Assurance]
  Package works out of the box with no prompting. There are no major bugs in Ubuntu and there are no major bugs in Debian. Unit tests are run during build.

  [Dependencies]
  All are in main. Note: libjs-bootstrap is only needed for the python-vitrageclient-doc binary package which does not need to be in main.

  [Standards Compliance]
  FHS and Debian Policy compliant

  [Maintenance]
  Simple python package that the OpenStack Team will take care of

  [Background]
  This is a client library for OpenStack Vitrage built to interface with the Vitrage API. Vitrage is the OpenStack RCA (Root Cause Analysis) service for organizing, analyzing and expanding OpenStack alarms & events, yielding insights regarding the root cause of problems and deducing their existence before they are directly detected.
