Hetzner DS does not configure private network interfaces

[dermotbradley]

Bug report

The Hetzner DataSource does not handle metadata server URLs of the form http://169.254.169.254/hetzner/v1/metadata/private-networks which are used to specify network interface configuration for interfaces attached to private networks.

Hetzner documentation for this is here: https://docs.hetzner.cloud/ and specifically the "Example: Private Networks" section shows an example of the information returned.

Steps to reproduce the problem

On Heztner Cloud:

• Create one, or more, private networks
• Create a cloud instance with at least one interface attached to a private network

Environment details

• Cloud-init version: all
• Operating System Distribution: all
• Cloud provider, platform or installer type: Hetzner

Thanks for the report. This would be a good thing for cloud-init to do.
