## What this PR does
In a previous patch (#1555) the reconciliation loop for the OpenAPI UI
resources was accidentally removed. This patch reintroduces a separate
controller, which handles updates to CozystackResourceDefinitions and
creates, updates, or deletes the dashboard's custom resources.
### Release note
```release-note
[dashboard] Reintroduce the accidentally removed reconciler that
autoconfigures custom dashboard resources for the OpenAPI UI.
