In a scenario where the client wants to completely uninstall Kueue (for example 1.0.1) so a new version can be installed, some Kueue CRs are getting stuck and never been completely deleted.

 Any version of Kueue (OCP 4.18 and 4.19)

   We should install Kueue Operator and Operand, create some configuration such as resourceflavor, clusterqueue and localqueue. After this, execute a job to get the worlkoad created and then, try to completely uninstall Kueue.

    1. Install Kueue Operator and Operand
    2. Create a resource flavor and cluster queue
    3. Create a namespace and local queue
    4. Run a job, to create a workload
    5. Go to Operators > Installed Operators > Click on the 3 dots > Uninstall Operator > Check the option "Delete all operand instances for this operator"
    

  On Installed Operators page, seems that Kueue was completely uninstalled. However, if we go to CustomResourceDefinitions and check Kueue CRs, some are showing "Resource is being deleted". This state is kept until some user interference, for example, finalizers deletion (picture attached).

    Kueue uninstall should handle all Kueue CRs and uninstall them properly.

    A way to get the CRs deleted, is to manually delete the finalizers.
