[ACTP] Use extra path to load sequentially

[merchristK]

What does this PR do?

Use extra config for privateactionrunner in node agent.

Motivation

When creating the privateactionrunner container in the node agent, we use -c datadog.yaml -c privateactionrunner.yaml! This is wrong because privateactionrunner.yaml overrides completely what was in datadog.yaml. The PAR supports -c for the default config and -E for any extra config added sequentially. See https://github.com/DataDog/datadog-agent/blob/7d218c7ab078722c59f6acbb6db918dadeca6794/cmd/privateactionrunner/command/command.go#L48-L49

Additional Notes

Anything else we should know when reviewing?

Minimum Agent Versions

Are there minimum versions of the Datadog Agent and/or Cluster Agent required?

• Agent: v7.76
• Cluster Agent: vX.Y.Z

Describe your test plan

Built the operator locally and deployed in docker-desktop ! I've then exec-ed into the pod and checked the config

# Build the operator image
make IMG=test/operator:dev docker-build

# Install CRDs
make install

# Deploy the operator
make IMG=test/operator:dev deploy

kubectx docker-desktop

cp .env.example .env

kubectl apply -k .
kubectl delete -k .
