[Bug 1915734] Re: The db-sync command fails with MySQL 8

[Chris MacNaughton]

** Description changed:

+ [Impact]
+ 
+ New installations of OpenStack Magnum with Mysql8 fail with a traceback
+ when trying to initialize the database
+ 
+ [Test Case]
+ 
+ Use the OpenStack charms to deploy Mggnum on Ubuntu Focal. Using Focal
+ is expected to have a traceback and with this change is expected to
+ setup successfully.
+ 
+ [Regression Potential]
+ 
+ The regression potential for this is minimal as the package currently
+ does not work at all with mysql8 which ships with Ubuntu Focal.
+ 
+ The proposed change is a cherry-pick from upstream that resolves this
+ issue by updating the old migrations to not set constraints that break
+ on Mysql8. This only affects new deploys that would normally step
+ through all of the old migrations so shouldn't affect running deploys.

  The command to do the Magnum DB sync ('magnum-db-manage upgrade') fails
  when using MySQL 8 releases.
  
  This issue is tracked in the upstream Magnum project at:
  https://storyboard.openstack.org/#!/story/2008488.
  
  There is a fix already merged on Magnum master branch to fix this:
  https://review.opendev.org/c/openstack/magnum/+/774142
  
  We need to have this fix included with Magnum distro packages that are
  expected to use MySQL 8. For example, deployments on Ubuntu Focal (or
  higher) are expected to be using MySQL 8 already.

  [Test Case]

  Use the OpenStack charms to deploy Mggnum on Ubuntu Focal. Using Focal

  [Regression Potential]

  The regression potential for this is minimal as the package currently
  does not work at all with mysql8 which ships with Ubuntu Focal and
  above. This change has already landed into the upstream project, both
  on Master and in their stable branches.

  The proposed change is a cherry-pick from upstream that resolves this
