Promotes a folder or file to a dataset. The supplied path is used to determine what entity is promoted.
Folders and files inside a source can be promoted to physical datasets. This converts the folder/file to a dataset; the dataset will have a new ID since it is a new entity.
To unpromote a dataset, you delete the dataset, which reverts it back to its original form (a folder or file).
400 - the supplied CatalogEntity object is invalid.
403 - user does not have permission to create the catalog entity.
