Service vaults

The service vault is needed when the system is operating in container mode. The service vault is created while container mode is being enabled and cannot be deleted until container mode is disabled. Only a single service vault can be created.

The service vault stores a mapping of container names to container vault, storage accounts, and access keys. Therefore, all container I/O fails when the service vault is not accessible from the access devices. If the content of the service vault is lost, the containers are lost as well.
