Public bug reported:

As listed at https://discourse.ubuntu.com/t/netbooting-the-live-server-
installer/14510/135

When attempting a netboot, we can end up in a situation where cloud-init
downloads a full iso, only to decide that the first few bytes aren't the
expected header and to ignore it.

I suggest an enhancement where a small amount of data is downloaded at
first, we check this data for the required #cloud-config, and then use
that info to decide to continue to download the file or not.
