The cloud-init status check in `pgbouncer-health-check` may not retry

I believe that there's a chance the loop in this status check doesn't work properly. If the status returns WAITING with a status of 2 then set -euo pipefail might fail this. I have a screenshot of SSM trying to run this command, then exiting with no message with a status of 2. The only explanation I could think of is exiting from the cloud-init status check.

A possible solution is to let cloud-init do the wait interally (--wait).
