API for edit/update credentials

[mkanazawa]

It would be great if updating the credentials of the data source could be executed via API.

Many features of Power BI can be automated via API, however, we have not been able to automate the process of publishing and refreshing reports because there is no API to edit/update credentials.

Currently the API grants the ability to update the connection string of a data source, but not the ability to update credentials.
