Audit-logs container was adjusted previously to handle SIGTERM using a trap and cleanup function. However due to behavior described here https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.23/#container-v1-core the `$$` used to grab PID is not properly interpreted. This issue is to fix the script to handle this behavior correctly and make the cleanup be consistent with the changes to apply-bootstrap container for a similar ignored SIGTERM issue.

    1. Create a hypershift cluster with auditing enabled
    2. Delete apiserver pods and observe the script does not correctly handle sigterm.
    3.
