Comment 6 for bug 1884071

Well, this does make cloud-config-archive support gzipped blobs, so in one way it fixes an issue that was reported. But the problem really seems to be that:

a.) Hetzner only supports (utf8?) strings in their user-data
b.) "terraform modules for templating cloud init hard depend base64 encoding on enabling gzip compression:"

Another option is just to add transparent decompression on the user-data blob that we get from hetzner. The problem with transparent decompression is you can't turn it off...

That change would look like this:
