SqlClient in .Net Core is missing SqlDataSourceEnumerator

[saurabh500]

SqlClient doesn't have SqlDataSourceEnumerator implementation in .Net Core.

This should also be exposed via SqlClientFactory

This was also mentioned here https://github.com/dotnet/corefx/issues/17126

Should this be moved to dotnet/sqlclient now, per https://devblogs.microsoft.com/dotnet/announcing-net-core-3-0-preview-5?

As recently announced in the .NET Blog, focus on new SqlClient features an improvements is moving to the new Microsoft.Data.SqlClient package. For this reason, we are moving this issue to the new repo at https://github.com/dotnet/SqlClient. We will still use https://github.com/dotnet/corefx to track issues on other providers like System.Data.Odbc and System.Data.OleDB, and general ADO.NET and .NET data access issues.

Will close this issue as #17 covers all missing APIs.
