this should not be an error, but we rather should set an appropriate condition on the HetznerCluster object, create an event, and return nil here.

I hope I understood you correctly here. I set the NetworkReadyCondition to false in that case. Also what do you mean with "create an event"?

What this PR does / why we need it:
This PR makes it possible to "adopt" a pre-existing network by passing its ID to
hetznerCluster.spec.hcloudNetwork.idinstead of the network being created during cluster creation. Furthermore, during cluster deletion it only deletes the attached network if it does not have theownedlabel attached to it (currently the only way here to discriminate between a CAPH-managed network and an unmanaged one).Which issue(s) this PR fixes (optional, in
fixes #<issue number>(, fixes #<issue_number>, ...)format, will close the issue(s) when PR gets merged):Fixes #762
Special notes for your reviewer:
This has been lingering around for a while untouched on my fork and I decided to rebase it onto the current main branch. Please consider this as a first attempt to approach this topic as a whole. I also tried to already add some unit tests. I guess it also might require some e2e tests!? No idea if this is the desired way to do this and about other side-effects I did not see. So looking forward for feedback or any pointers. And also feel free to push changes to the PR, as I'll be pretty occupied with other things almost the whole September. Just wanted to push this out there already for you to take a look at 🙂
The most controversial changes so far:
hcloudNetwork.idmutually exclusive withcidrBlock,subnetCidrBlockandnetworkZonecidrBlock,subnetCidrBlockandnetworkZoneto be pointers (I guess this could also be done with empty strings, but pointers make it possible to be not shown at all, when not provided)Please confirm that if this PR changes any image versions, then that's the sole change this PR makes.
