Subject: [PATCH] providers/hetzner: fix duplicate attribute prefix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The attributes generated for the hetzner provider had a duplicate
prefix:
AFTERBURN_AFTERBURN_HETZNER_HOSTNAME=flatcar-test
Afterburn already adds the prefix itself in src/providers/mod.rs
`MetadataProvider.write_attributes()`, so the additional prefix added in
the hetzner provider was unnecessary.

Subject: [PATCH] providers/hetzner: private ipv4 addresses in attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds new attributes `AFTERBURN_HETZNER_PRIVATE_IPV4_*` set to the
servers IPv4 addresses in private networks.
This is useful for e.g. discovery of etcd members that should
communicate over the private network.
