RS_SHPWFE : Installs Reporting Services Add-In for SharePoint products.

Option to add to the DSC Resource :
/RSINSTALLMODE Specifies the Install mode for Reporting Services. Supported Values: SharePointFilesOnlyMode,DefaultNativeMode,FilesOnlyMode Was added in PR https://github.com/PowerShell/SqlServerDsc/pull/1361.

Start with the SqlSetup DSC resource and review how existing SQL Server installer features and options are represented. Compare the resource with the installer options for RS_SHP and RS_SHPWFE, then check the related PR mentioned in the issue. Done means the missing Reporting Services features are supported by the resource and validated against the stated SQL Server versions.
