  /**
   * Create a ServiceUpdateDescription.
   * @property {string} [flags] Flags indicating whether other properties are
   * set. Each of the associated properties corresponds to a flag, specified
   * below, which, if set, indicate that the property is specified.
   * This property can be a combination of those flags obtained using bitwise
   * 'OR' operator.
   * For example, if the provided value is 6 then the flags for
   * ReplicaRestartWaitDuration (2) and QuorumLossWaitDuration (4) are set.
   *
   * - None - Does not indicate any other properties are set. The value is
   * zero.
   * - TargetReplicaSetSize/InstanceCount - Indicates whether the
   * TargetReplicaSetSize property (for Stateful services) or the InstanceCount
   * property (for Stateless services) is set. The value is 1.
   * - ReplicaRestartWaitDuration - Indicates the ReplicaRestartWaitDuration
   * property is set. The value is  2.
   * - QuorumLossWaitDuration - Indicates the QuorumLossWaitDuration property
   * is set. The value is 4.
   * - StandByReplicaKeepDuration - Indicates the StandByReplicaKeepDuration
   * property is set. The value is 8.
   * - MinReplicaSetSize - Indicates the MinReplicaSetSize property is set. The
   * value is 16.
   * - PlacementConstraints - Indicates the PlacementConstraints property is
   * set. The value is 32.
   * - PlacementPolicyList - Indicates the ServicePlacementPolicies property is
   * set. The value is 64.
   * - Correlation - Indicates the CorrelationScheme property is set. The value
   * is 128.
   * - Metrics - Indicates the ServiceLoadMetrics property is set. The value is
   * 256.
   * - DefaultMoveCost - Indicates the DefaultMoveCost property is set. The
   * value is 512.
   * - ScalingPolicy - Indicates the ScalingPolicies property is set. The value
   * is 1024.
   * @property {string} [placementConstraints] The placement constraints as a
   * string. Placement constraints are boolean expressions on node properties
   * and allow for restricting a service to particular nodes based on the
   * service requirements. For example, to place a service on nodes where
   * NodeType is blue specify the following: "NodeColor == blue)".
   * @property {array} [correlationScheme] The correlation scheme.
   * @property {array} [loadMetrics] The service load metrics.
   * @property {array} [servicePlacementPolicies] The service placement
   * policies.
   * @property {string} [defaultMoveCost] The move cost for the service.
   * Possible values include: 'Zero', 'Low', 'Medium', 'High'
   * @property {array} [scalingPolicies] Scaling policies for this service.
   * @property {string} serviceKind Polymorphic Discriminator
