Enable multi column group by for Dataframe

[trilochan]

System information

• OS version/distro:windows
• .NET Version (eg., dotnet --info): .net core 5.0

Issue

I am using the Dataframe object from Microsoft.Data.Analytics, currently GroupBy only allows to group by only one column. There isn’t an option to group by multiple columns.

• What did you do?
• created a Dataframe with a few columns
• What happened?
• tried to use group by multiple columns
• What did you expect?
• Expected a method that took a list of columns names to group the Dataframe by
