[tc][all] Call to review Train goal proposals

Hello everyone, As you might have seen, we have two community goals available for review. Adrian has proposed a goal [1] for cleaning up resources when deleting a project. Artem has a review up [2] detailing the legacy client work for Train. Your input would be very welcomed. This is an important step to improve OpenStack, and we hope those reviews will get the attention they deserve! Thank you, Lance & Jean-Philippe [1]: https://review.openstack.org/#/c/639010/ [2]: https://review.openstack.org/#/c/639376/
