[BUG] private_networking depricated and insufficient for DigitalOcean salt-cloud interface

[waynegemmell]

Description
The Digialocean APT has depricated the private_networking option when creating a new droplet. It needs to be replaced with the vpc_uuid field in order to target which vpc you wish to attach to the droplet that's being created.

This is fairly important as you can have multiple VPC's (Virtual Private Cloud) setup per data center but you can only attach one VPC to each droplet and as such you need to request the appropriate one. This is not transferable so cannot get rectified at a later stage.
