Feature Request: Add ability to create streams on existing data sets.

[BaReinhard]

We recently had to create new credentials for a custom application since the past client credentials expired due to the user no longer being active in domo. The new credentials do not have a stream available for the dataset, it appears that there is no current way to create a stream on an existing dataset. This requires us to export and subsequently import the large dataset to begin publishing data to domo.
