	// Provisioning state machine:
	//
	// From ARM's perspective, Succeeded and Failed are the only two terminal
	// provisioning states for asynchronous operations.  Clients will poll PUT,
	// PATCH or DELETE operations until the resource gets to one of those
	// provisioning states.
	//
	// ARO uses Creating, Updating and Deleting as non-terminal provisioning
	// states to signal asynchronous operations from the front end to the back
	// end.
	//
	// In case of failures, the back end sets failedProvisioningState to the
	// provisioning state at the time of the failure.
	//
	// The ARO front end gates provisioning state machine transitions as
	// follows:
	//
	// * no PUT, PATCH or DELETE is accepted unless the cluster is currently in
	//   a terminal provisioning state.
	//
	// * DELETE is always allowed regardless of the terminal provisioning state
	//   of the cluster.
	//
	// * PUT and PATCH are allowed as long as the cluster is in Succeeded
	//   provisioning state, or in a Failed provisioning state with the failed
	//   provisioning state to Updating.
	//
	// i.e. if a cluster creation or deletion fails, there is no remedy but to
	// delete the cluster.

	// LastProvisioningState allows the backend to see the last terminal
	// ProvisioningState.  When they complete, regardless of success, admin
	// updates always reset the ProvisioningState to LastProvisioningState.
