Migrate 'containerbuildsystem/osbs-box' to 'Webhook To Fedora Messaging'

[gridhead]

This project was listed in the GitHub2FedMsg database and we want to you to inform you about the upcoming deprecation of the service. As the Fedora Infrastructure is finishing up with migrating its applications away from FedMsg to Fedora Messaging, we encourage you to migrate your repository to the successor of the GitHub2FedMsg project, Webhook To Fedora Messaging.

Please follow this link to the official announcement of the project’s release and use the instructions there to migrate to the new service. If this notification was a mistake, please close this notification ticket. We will not act on the repositories whose migrations have not been requested and any related GitHub2FedMsg operations will stop working once the service is decommissioned.
