Fix ingress rules delete job
Related tasks
Context
When calling the prepare upstream deletion pre-hook, the StartSimulation state was being used instead of the StopSimulation one. After fixing that, we needed a mechanism to get the upstream name.
Change
This MR includes a pre-hook to get the upstream name before deleting the gloo ingress rules.
Other information
This MR also changes the namespace where ingress rules are being deleted from.
