Description

There is a similar pr open for the kubernetes libs, but there haven't been any updates in a few weeks.

In the comments of that pr there is a comment:

yes we plan to upgrade the controller-runtime to v0.15+, but it has breaking changes and may need more time and efforts to investigate and implement corresponding changes. I think we need to do it sooner than later. Any community contribution is very welcome. Thanks.

This PR is to address the k8s 1.29 dependency updates and refactoring required (the bulk of the changes) to update the controller runtime to v0.15+. Also sets the go version 1.22.

Two tests were removed that were related to decoder injection that is no longer possible in new versions of controller runtime. Two other tests were removed that checked ingresses were deleted there was a deletion timestamp with no finalizer. This is no longer possible because controller-runtime sets the DeletionTimestamp to nil on Create(). Because of this the DeletionTimestamps were also removed from the deleted ingress with finalizer tests.
