* Endpoint.Target is now Endpoint.Targets. This is its own type representing mutliple targets for a single DNS name while adding some convenience for sorting and comparing
* Made everything compile and tests run through with the new Endpoint.Targets
* The ingress source can now properly handle multiple target ips per host
* Added custom conflict resolver, to better understand how conflict resolution has to work for me
* My custom conflict resolver behaves a bit different than the PerResource resolver, therefore I needed to modify the expected test result
Removed unnecessary FIXME
* The ingress source now creates CNAME endpoints with multiple targets to let the DNS provider decide how to handle multiple CNAME targets. This could be interesting for weighted targets etc.
* Adopted the expected results to the new way we create endpoints for CNAMEs
* Removed Add method from Targets since manipulating the slice through here is unnecessary complicated and doesn't deliver enough convenience
* Reverted ConflictResolver to the original one. There is some discussing to do what the best way is to handle conflicts
* Added missing documenting comment to IsLess of Targets
* Added documenting comments to Targets,Targets.Same and NewTargets to clarify their intention and usage
* Service source now also generates endpoints with multiple targets
* Service and Ingress source now sort all Targets for every Endpoint to make order of Targets predictable
* Endpoints generated by the Google Cloud DNS provider now also have sorted Targets to make order of Targets predictable
* Modified provider dyn to be able to compile with multi target changes
* Fixed small nitpicks, so my code is acceptable
* Fixed merge method after updating to new Targets. Replacing '!=' with .Same of course needs a boolean negation
* Tests for dyn provider now also use the new Targets instead of Target
* Simplified extractServiceIps as implied by linki to make it more readable
* ref: change service ClusterIP retrieval again
* Added entry to CHANGELOG.md describing the new features contained in this PR
* feat(plan): allow plans to be parameterized via policies
* fix(controller): set a policy in the controller tests
* chore: allow go tip to fail
* chore: update changelog to include policies
* fix(plan): store a pointer to changes
* fix(controller): don't get address of a pointer
