Changes to mk_kvm to allow Ubuntu 14.04 VMs

Not working on CentOS 6 KVMs
Add new cookbooks as submodules
Add verify_api_cert to solo.rb
Refactor attributes out, implement Apache2 standard cookbook

Untested in CentOS5/6
Use own apache2 cookbook fork

Opscodes COOK-3900 doesn't work well:
* Add unused cookbooks required by Apache2 as dummies: empty dirs and metadata
General tweaks to get platform independent setup
Made netcfg.cgi hardlinks soft

(Because they weren't hardlinks!)
