The bed enforces one-push provisioning and a patient runtime (057/058)

The provider's workaround re-push is gone: pushing the consumer's node
must cascade to the provider (issue 057), and the vhost assertion is
what says so. The joined consumer must also show zero container-runtime
restarts (issue 058): a runtime whose broker is not up yet waits for it
in-process, so overlay-after-container ordering produces no churn.
