[Conrad Hoffmann <ch@xxxxxxxxxxxxx>]

Conrad Hoffmann has proposed merging ~bitfehler/cloud-init:bitfehler/arch-netplan into cloud-init:master.

Commit message:
Support netplan renderer in Arch Linux
    
Support is for now implemented in such a way that it will fall back to
the old `_write_network()` if netplan is not available on the image.

Requested reviews:
  cloud-init commiters (cloud-init-dev)

For more details, see:
