Refactored the code to make it more maintainable.

- Redid the code for the cloud to be able to specify subnets, with the default based on bridge number. It now adds a bridge every time you run it.

- The creating if the VM now prompts you for a bridge to select if there is more than one, and prompts you to select storage if there is more than 1

- The No Subcriber nag removal will now last through Proxmox updates
