// Initiates a flow to start a new task contact. For more information about task
// contacts, see Concepts: Tasks in Amazon Connect (https://docs.aws.amazon.com/connect/latest/adminguide/tasks.html)
// in the Amazon Connect Administrator Guide. When using PreviousContactId and
// RelatedContactId input parameters, note the following:
//   - PreviousContactId
//   - Any updates to user-defined task contact attributes on any contact linked
//     through the same PreviousContactId will affect every contact in the chain.
//   - There can be a maximum of 12 linked task contacts in a chain. That is, 12
//     task contacts can be created that share the same PreviousContactId .
//   - RelatedContactId
//   - Copies contact attributes from the related task contact to the new contact.
//   - Any update on attributes in a new task contact does not update attributes
//     on previous contact.
//   - There’s no limit on the number of task contacts that can be created that
//     use the same RelatedContactId .
//
// In addition, when calling StartTaskContact include only one of these
// parameters: ContactFlowID , QuickConnectID , or TaskTemplateID . Only one
// parameter is required as long as the task template has a flow configured to run
// it. If more than one parameter is specified, or only the TaskTemplateID is
// specified but it does not have a flow configured, the request returns an error
// because Amazon Connect cannot identify the unique flow to run when the task is
// created. A ServiceQuotaExceededException occurs when the number of open tasks
// exceeds the active tasks quota or there are already 12 tasks referencing the
// same PreviousContactId . For more information about service quotas for task
// contacts, see Amazon Connect service quotas (https://docs.aws.amazon.com/connect/latest/adminguide/amazon-connect-service-limits.html)
// in the Amazon Connect Administrator Guide.
