* added WorkspaceFeatures.cs

* updated version from .23 to .24

* ran autorest code

* added the .txt file needed for PR

* re ran the generage.ps1 script - so it now includes operationalinsights_resource-manager.txt

* moved DataExport.cs to Customization folder to avoide deletion by autorest.
this file contains a manual change from auto gen code

* made DataExport.cs under Customization folder a partial class that only contains the missing inheritance, left all other autogen code as is
