Use different data sources with the same database and different credentials

[b1c1jones]

With Reference to Add two different credentials for same data source in Power BI Service , add ways to have different data sources that point to the same database and with different logins. Use case: Using Row Level Security (RLS) by login on a single database, so use same database source for different pbix with the same login, so when working in Desktop the credentials don't have to be re-entered for each login in different pbix sessions plus the data source can be identifed with a parameter and point to different logins, possibly allowing the same pbix to be used with different logins.

Note that attempted to use alias urls to work around this, however with a PostgreSQL database and SSL this doesn't work because it results in a certificate error and the main database is an AWS RDS which we can't modify the root certificate of.
