   * Session represents provisioning a single template import or workspace.  The daemon always sends Config followed

   * of zero or more Logs, followed by the corresponding complete message (ParseComplete, PlanComplete,
   * ApplyComplete).  The daemon may then send a new request.  A request to apply MUST be preceded by a request plan,
   * and the provisioner should store the plan data on the Session after a successful plan, so that the daemon may
   * request an apply.  If the daemon closes the Session without an apply, the plan data may be safely discarded.
   *
   * The daemon may send a CancelRequest, asynchronously to ask the provisioner to cancel the previous ParseRequest,
   * PlanRequest, or ApplyRequest.  The provisioner MUST reply with a complete message corresponding to the request
   * that was canceled.  If the provisioner has already completed the request, it may ignore the CancelRequest.
