One bad module must not drop its node: the provisioner composes each module's plan on its own (issue 774)

novox since 15:36 (nats's built manifest) and ace since 15:37 (baserow's config.json) had no plans at all, so the
vault refused every secret their clients asked. The holder now composes with frombus.PlansHeld: a module whose build
or plan refuses is held, its why kept in the new state refused and read by provisioner_plans, its last plan and its
provisions left as they were, and every other module on the node composed and written. Pins mesh-sdk 59311407.
