Update the CDN APIs on different language examples

[leibaogit]

Since the old VDMS CDN (SoftLayer_Network_ContentDelivery) was sunset, but we can still the APIs present in the different language examples. In the mean while, the new CDN (SoftLayer_Network_CdnMarketplace) was GAed at 2017, but we can not see the new APIs in all languages.

1. Remove the legacy CDN APIs
   • GO https://sldn.softlayer.com/go/cancel_cdn.go/ https://sldn.softlayer.com/go/get_cdn_list.go/ https://sldn.softlayer.com/go/place_order_cdn.go/

• Perl https://sldn.softlayer.com/perl/place_order_cdn.pl/

• PHP https://sldn.softlayer.com/php/PlaceOrderCDN.php/

• Ruby https://sldn.softlayer.com/ruby/cancel_cdn.rb/ https://sldn.softlayer.com/ruby/place_order_cdn.rb/

2. Add new CDN APIs for all languages.

We do have a few examples on the CdnMarketplace APi: Python - https://sldn.softlayer.com/python/cdn_network.py/ Golang - https://sldn.softlayer.com/go/CDN_services.go/ Ruby - https://sldn.softlayer.com/ruby/cdn_network.rb/

I'm not an expert on the CDN stuff, so if those need updating or anything, please let me know.

In the mean time, well remove those listed examples.

Thanks.
