function Get-DbaFeature {

    .SYNOPSIS
        Runs the SQL Server feature discovery report (setup.exe /Action=RunDiscovery)
 
    .DESCRIPTION
        Runs the SQL Server feature discovery report (setup.exe /Action=RunDiscovery)
 
        Inspired by Dave Mason's (@BeginTry) post at
        https://itsalljustelectrons.blogspot.be/2018/04/SQL-Server-Discovery-Report.html
 
        Assumptions:
        1. The sub-folder "Microsoft SQL Server" exists in $env:ProgramFiles,
        even if SQL was installed to a non-default path. This has been
        verified on SQL 2008R2 and SQL 2012. Further verification may be needed.
        2. The discovery report displays installed components for the version of SQL
        Server associated with setup.exe, along with installed components of all
        lesser versions of SQL Server that are installed.
 
    .PARAMETER ComputerName
        The target computer. If the target is not localhost, it must have PowerShell remoting enabled.
 
        Note that this is not the SqlInstance, but rather the ComputerName
 
    .PARAMETER Credential
        Allows you to login to servers using alternative credentials. To use:
 
        $cred = Get-Credential, then pass $cred object to the -Credential parameter.
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
