IIS : implement authenticationinfo in iis_site

Use case is to disable Anonymous and enable Windows Authentication, which is pretty standard.

Desired Behavior:

The ability to manage authentication at the site level.

Actual Behavior:

The IIS module only allows for authenticationinfo to be used within iis_application and not iis_site.

Workaround:

This is PowerShell to run to after feature delegation has been set:

Set-WebConfigurationProperty -Filter /system.webserver/security/authentication/anonymousAuthentication -name enabled -value false -PSPath 'IIS:\Sites\Default Web Site'

Set-WebConfigurationProperty -Filter /system.webserver/security/authentication/windowsAuthentication -name enabled -value true -PSPath 'IIS:\Sites\Default Web Site'
