SqlWindowsFirewall: For feature RS it should not create rules for both port 80 and 443 by default

Details of the scenario you tried and the problem that is occurring:
Today when feature 'RS' is sent to xSQLServerFirewall it will open up both ports 80 and 443. The user should be able to decide which port or ports to open.

The DSC configuration that is using the resource (as detailed as possible):

xSQLServerFirewall FirewallConfiguration
{
    Ensure = 'Present'
    SourcePath = $Node.SourcePath
    InstanceName = $Node.InstanceName
    Features = 'RS'

    PsDscRunAsCredential = $SqlInstallCredential
}

Version of the Operating System, SQL Server and PowerShell the DSC Target Node is running:
Any

What module (SqlServer or SQLPS) and which version of the module the DSC Target Node is running:
n/a

Version of the DSC module you're using, or 'dev' if you're using current dev branch:
Dev

Start at the xSQLServerFirewall resource and trace how Features = 'RS' is translated into firewall rules. Review the resource's existing tests, if available, and confirm the completed behavior against the requirement that RS should not unconditionally create rules for both ports 80 and 443.
