This deals with various breaking changes in controller-runtime, as
documented in the release notes:
https://github.com/kubernetes-sigs/controller-runtime/releases/tag/v0.15.0
In short:
- `Watches` now use a `client.Object` instead of a `source.Kind`.
- `handler.MapFunc` signature accepts a Go context, which is used to
log any errors, instead of silently ignoring them and/or panicking.
- Fake clients used in tests are now configured using
`WithStatusSubresource` to enable the correct behavior for status
updates and patches.
- Max concurrent reconciles is configured on the manager, instead of
configuring them per reconciler instance.
- Various manager configuration options have been moved to new
structures and/or fields.
In addition to this, all other dependencies which had updates are
updated to their latest (compatible) versions as well.
