Hetzner causing rate limit error and not handling it correctly

[yelhouti]

What happened:
Hetzner not creating records due to rate limit error, and not handle it correctly (ie: slowing down).

What you expected to happen:
to detect rate limit and slow down, although the detection should be handled by: https://git.blindage.org/21h/hcloud-dns/src/commit/d31cdce4149f7248e6d08adec2ca5a81ff150ce5/zones.go#L92 which doesn't check the response status code and unmarshales to the wrong type, creating the illusion of no error.

Use CreateRecordBulk and UpdateRecordBulk to avoid reaching the limit at the first place.

How to reproduce it (as minimally and precisely as possible):
just use hetzner with a cluster with many ingresses.

Environment:

• External-DNS version (use external-dns --version): 1.7.1
• DNS provider: Hetzner
• Others:

Workaround:

Edit: /run/systemd/resolve/resolv.conf
Remove IPv6 Resolver.

Please note that we removed the Hetzner provider due to a DOS attack from the library provider. See #2660 for future follow ups.
