[mmat11]

Description

This PR adds the ebpf tracing agent subchart

How Has This Been Tested?

1. Package the new chart:
   • Set domain and clusterName in the values.yaml file
   • helm lint ./otel-integration/k8s-helm
   • helm dependency build ./otel-integration/k8s-helm
   • helm package ./otel-integration/k8s-helm
2. Create a new namespace on the cluster: k create ns test-ebpf-agent-subchart
3. Create a new coralogix-keys secret: k create secret generic coralogix-keys -n test-ebpf-agent-subchart --from-literal=PRIVATE_KEY=bogus
4. Install the chart while setting enabled=true for the subchart: helm install cx-otel-shippers /Users/mattia.meleleo/cx/telemetry-shippers/otel-integration-0.0.114.tgz --namespace test-ebpf-agent-subchart --set coralogix-ebpf-agent.enabled=true
5. Observe the created resources are running as expected
