Tableau ingestion to support multiple dataset platform instances of the same platform type

[richenc]

In the Looker ingestion, there is a parameter called connection_to_platform_map that allows you to map platform instances to a connection/datasource. With this config, you can support a use case such as having multiple snowflake platform instances. However, in the Tableau ingestion, only platform_instance_map is supported, which maps 1 platform instance per platform and doesn't take into account the data source/connection.

Expected behavior: I am able to configure something similar to connection_to_platform_map where I can indicate which Tableau data source maps to which dataset platform instance's database

See https://github.com/datahub-project/datahub/pull/10254. I think this improves the mapping situation, but there is still the case where the database server doesn't have a hostname. It will still retain the original, undesired behavior in that case. I also did not find a way to manually configure the hostname on the Tableau side.
