feat(utils): add script to clear finalizers and delete stuck OpenShift projects

[RishabhKodes]

The script cleans up OpenShift projects stuck in the Terminating stage by removing resource and project finalizers, then initiating deletion.

• Detects dangling resources/finalizers from project status
• Patches each remaining resource to remove /metadata/finalizers
• Removes project-level finalizers
• Triggers non-blocking project deletion

Note: This is the first version of the script and has been tested only with ELM (not EIC); do not merge it yet.

is this the same code as in the previous paragraph just for namespaced resources? Can we combine the two paragraphs and reuse the code?

[RishabhKodes]

It's not exactly the same however the idea behind both the sections of code is the same. I would not combine the two because their functionalities are different and we might need to modify each of them later depending on the types of resources that we might come across that need to be deleted later (for an edge case).

I would like to be very catious about || true in the code. From my point of view we expect these commands not fail. So why do we need || true - looks like a path to not to remove some resources and skip errors. What do you think?

[RishabhKodes]

Ideally, the || true ensures that the script continues even if a command fails; these commands don't usually fail because it's just patching, but even if they do, it doesn't hamper the execution of the script. This is to ensure maximum resource removal even if some parts fail.

[kksat]

should we add maybe check that there are not dangling resources at the end? and fail if there are still some resources.
