fix slice delete issue

[asm582]

On OpenShift SNO install slices were not deleted in some instances. The root cause of this issue is unknown as it is not reproducible on the KinD cluster; one theory is that multiple NVML init calls could cause non-determinism in slice discovery, and an issue is opened for such a use case in #225. This PR has improved logging when a slice is not found and retries when a slice is not found, but the config map for workload still exists in the system.

make test ,make lint, make test-e2e and daemonset shell script all pass locally.
