tempest tests failing with "Cannot complete the requested action because chassis NN contains nodes."

[aeva black]

Tempest tests' tearDownClass call is failing randomly with an error that the chassis can not be deleted because it contains nodes. Ironic does not cascade-delete nodes when deleting a chassis, so this error is valid, and indicates that tempest should have cleaned up the nodes prior to deleting the chassis.

For example:

Should be fixed by https://review.openstack.org/#/c/122832/

This was incorrectly categorized (by me) in Ironic, instead of in Tempest (where it was actually fixed).

Closing it here since it is odd to have an unassigned+fix_committed bug with no commits in the project.
