providers/hetzner: add support for Hetzner Cloud #1707

Hetzner Cloud employee here 👋 Looks good from a metadata service perspective.
We do have a go metadata client, but I think that's overblown for this specific use case. (And I just noticed that its missing the userdata endpoint anyway)
Some notes about general support for Ignition metadata in Hetzner Cloud:
- The
hcloudCLI has somecloud-initspecific helper utility when users pass in multiple files using thehcloud server create --user-data-from-fileflag. I do not think that specifying multiple files makes sense in Ignition (they would need to be merged somehow) - The "Create Server" page in the web console has some cloud-init specific help text for the User Data input
|
Yes, I noticed the cloud-init specifics as well. From a technical standpoint, I did some testing where I "chain-load" the Ignition config from your userdata service, and it works as expected. (see https://github.com/mhutter/hcloud-packer-coreos/blob/7c11c5a774c05ba3b4df388e4cc1a82d8a2a5d05/files/chain.bu) The rest I just ignored :D |

@mhunter Thank you so much for putting in the time and effort on adding hetzner.
After looking over this everything looks great, I just have a small nit on the commit
I would prefer it to be "providers/hetzner: add support for Hetzner Cloud" there are no guidelines for this, but I know in this repo we tend to have our commits be in the form of "providers/xyz: work that was done"
* Add Hetzner Cloud as a provider * Userdata endpoint is http://169.254.169.254/hetzner/v1/userdata Signed-off-by: Manuel Hutter <manuel@hutter.io>

@prestist Ah, I see! I only looked at the last couple of commits, but they're all dependabot commits. I have amended my commit accordingly 👍 |

@apricote Any idea when we'll be able to provision CoreOS cloud or dedicated images at Hetzner? I'd really like to migrate my servers. |

I'm not sure what that linked comment says, honestly. Seems like the CoreOS engineers need information about the Hetzner platform, which I believe Hetzner should provide, not a regular end-user like me. I just wanted to express my interest, not be the one to open PRs and do the work for Hetzner ;) |
Figured out this is actually trivial, so here's a PR.
Supersedes #667 and #1262 which I cannot push commits to.
