Allow to download files related to cloud-init via http(s)

[witsch]

With this URLs can be specified instead of local files for --bootconf, --config, --userdata, --metadata and --file.

Thank you @witsch that sounds Like a super cool feature! I‘ll have a look at it soon.

Hmm, unfortunately the tests fail, but locally I've had the same strange failure for the "cloud-init: flash --metadata replaces meta-data" test I borrowed from…

> flash-test@0.0.1 test /code
> if [ -e ../node_modules/.bin/bats ]; then ../node_modules/.bin/bats --tap test; else node_modules/.bin/bats --tap test; fi

I suppose I'll leave that assertion out of the new one as setting the hostname correctly is actually unrelated to downloading the file, right?

Oops, turns out to be a bad "copy & paste"… 😊 It should be fixed in 024db1f88adfc5bca3069ba77243b232ae0394a9.

Thank you, that's really convenient, I can put my user-data file to GitHub :-)

Yes, that was the idea… after I recently got a new Pi and found HyprioOS (big props, btw) I started playing with Docker stacks (and I suppose that was mainly because of that blog post you guys put up), but most of the examples I found were either using compose or didn't quite work out of the box. Or at least for me, albeit not being very familar with the topic didn't help… 🙂

Anyway, after figuring a few things out I thought it might be useful to make it available somewhere, and at that point it just seemed nice to be able to avoid the extra step of downloading an example user-data file to get you started. But now I can… 😄
