Must gather script can now collect memory and CPU usage via container exec and also captures cgroup limits, requests, and throttling stats.
Outputs the info to "must-gather/namespaces/"namespace"/pods/"pod-name"/"container-name"/"container-name"/resources/". Creates files to track what each does
last.terminated: Provides an error message on why the previous container crashed if applicable. Helpful for identifying errors like Out of memory.
memory.pressure / cpu.pressure: Tracks how much time the pod spends waiting for CPU or memory to become available. This helps identify if the pod is slowing down because the node is too busy.
