Tonic Structural release notes

Zones for workspace job routing - Self-hosted customers can optionally group their Structural workers into zones. The list of zones is configured on a new Zones tab on Structural Settings. In the worker, you use the environment setting TONIC_WORKER_ZONE_ID to assign the worker to a zone. The workspace settings include a new Zone option to select the zone to route the workspace jobs to. By default, a workspace is not assigned to a zone, and the workspace jobs are routed to a worker that is not assigned to a zone. Structural Cloud has its own set of zones for users to choose from for their workspaces, as well as a set of workers that are not tied to zones.
