// Creates an DMS event notification subscription. You can specify the type of
// source (SourceType) you want to be notified of, provide a list of DMS source IDs
// (SourceIds) that triggers the events, and provide a list of event categories
// (EventCategories) for events you want to be notified of. If you specify both the
// SourceType and SourceIds, such as SourceType = replication-instance and
// SourceIdentifier = my-replinstance, you will be notified of all the replication
// instance events for the specified source. If you specify a SourceType but don't
// specify a SourceIdentifier, you receive notice of the events for that source
// type for all your DMS sources. If you don't specify either SourceType nor
// SourceIdentifier, you will be notified of events generated from all DMS sources
// belonging to your customer account. For more information about DMS events, see
// Working with Events and Notifications
// (https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Events.html) in the
