agent crashes with loadFiltermanagerObjects failed

**Describe the bug**
retina-agent fails to start and crashes with the following error:

```
$ kubectl logs retina-agent-mdbr7 -n retina
Defaulted container "retina" out of: retina, init-retina (init)

```

**To Reproduce**
Steps to reproduce the behavior:

Installation command:
```
helm template retina oci://ghcr.io/microsoft/retina/charts/retina \
--version v0.0.12 \
--namespace retina \
--set image.tag=v0.0.12 \
--set operator.tag=v0.0.12 \
--set logLevel=debug \
--set os.windows=false \
--set operator.enabled=false \
--skip-crds \
--set enablePodLevel=true \
--set remoteContext=true \
--set enabledPlugin_linux="\[packetforward\,linuxutil\,dns\]" | kubectl apply -f -
```

It seems some issue with pod level toggle. If i set it to _false_, pods start normally.

**Expected behavior**
Clean initialization of retina-agent pods.

**Platform (please complete the following information):**
- Host: EKS
- Kernel Version: 5.15.153
- OS Image: Bottlerocket OS 1.19.5 (aws-k8s-1.27)

Thanks for any light in figuring it out what is happening.
