    """Describes an update for a stateful service.

    :param 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.

     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)".
