logzio-telemetry v4.0.0 (#416)

* Use K8S 360 metrics list from values

- Deleted the kubernetes-360-metrics key from the logzio-secret.
  - Populate the pods containers env var directly using the opentelemetry k8s360 definition to inherit the list from values file instead.
- Added logzio_app label with kubernetes360 value to cadvisor metrics to avoid dropping specific metrics.

* Update README.md

* Upgrade to v4 as it's a breaking change

 ## Change log
+* 4.0.0
+  - **BREAKING CHANGES**:
+    - Removed the `kubernetes-360-metrics` key from the `logzio-secret`.
+      - Populate the pods containers `K8S_360_METRICS` environment variable directly using the opentelemetry-collector.k8s360 definition to inherit the list from values file instead.
+  - Added `logzio_app` label with `kubernetes360` value to cadvisor metrics pipeline to avoid dropping specific metrics by matching the k8s 360 filter.
 * 3.0.0
   - Updated K360 metrics list in `secrets.yaml` - now created dynamically from OOB filters.
   - Added `job_dummy` relabel and processor - Fixing an issue where duplicate metrics were being sent if the metrics were not in the `K8S_360_METRICS` environment variable.
