mesh-tools 97a2d841c7 Land feature 57's controller work on its release branch
The controller plans config, templates and moved providers' provisions,
hands bus accounts to the vault and judges the new manifest words, on the
feature's SDK and node-engine validator (feature 57, config and provisioning).
