Issue:
[Feature] Remove support for Google OpenCensus relative codes.
### Search before asking

- [X] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar feature requirement.


### Description

OC is sunsetting, and going to dead soon.
Ref https://opentelemetry.io/blog/2023/sunsetting-opencensus/

AFAIK, we have fully immigrated into otlp metric format months ago.

@kezhenxu94 Please take a look and confirm. Let's remove all relative codes, docs, configurations once it is confirmed.

 ### SCOPE `EndpointRelation`
 
 This calculates the metrics data of the dependency between endpoints.
 This relation is hard to detect, and it depends on the tracing library to propagate the previous endpoint.
-Therefore, the `EndpointRelation` scope aggregation comes into effect only in services under tracing by SkyWalking native agents,
-including auto instrument agents (like Java and .NET), OpenCensus SkyWalking exporter implementation, or other tracing context propagation in SkyWalking specification.

Note that when using environment variables to pass this configuration, use single quotes(`''`) to avoid being evaluated by the shell.                                                          | -                                                 |                                                                                              |

 Istio should be installed in a Kubernetes cluster. Simply follow the steps in [Getting Started in Istio](https://istio.io/docs/setup/getting-started/).
 
-## Deploying SkyWalking backend
+## Deploy SkyWalking backend
 
 Follow the steps in [deploying backend in Kubernetes](../backend/backend-k8s.md) to install the OAP server in the Kubernetes cluster.
 Refer to [OpenTelemetry receiver](../backend/opentelemetry-receiver.md) to ingest metrics.
-`otel-receiver` is disabled by default. Set env var `SW_OTEL_RECEIVER` to `default` to enable it.
 
 
-## Deploying OpenTelemetry Collector
+## Deploy OpenTelemetry Collector
 OpenTelemetry Collector is the location where Istio telemetry sends metrics, which are then processed and shipped to SkyWalking
 backend.
 
-To deploy this collector, follow the steps in [Getting Started in OpenTelemetry Collector](https://opentelemetry.io/docs/collector/getting-started/). Several components are available in the collector, and they could be combined for different use cases.
-
-For the sake of brevity, we use the Prometheus receiver to retrieve metrics from Istio control and data plane,  then send them to SkyWalking by OpenCensus exporter.
-
-#### Prometheus Receiver
-Refer to [Prometheus Receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/150692dbbceb3ff0df75c912e835f1feaac0be93/receiver/prometheusreceiver/README.md)
- to set up this receiver. You could find more configuration details in [Prometheus Integration of Istio](https://istio.io/latest/docs/ops/integrations/prometheus/#configuration)
- to figure out how to direct Prometheus Receiver to query Istio metrics.
- 
-SkyWalking supports receiving multi-cluster metrics in a single OAP cluster. A `cluster` label should be appended to every metric
-fetched by this receiver even if there's only a single cluster needed to be collected.
-You could use `relabel` to add it, like this:
-
-```
-relabel_configs:
-- source_labels: []
-  target_label: cluster
-  replacement: <cluster name>
-```
-
-or you can do so through [Resource Processor](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/a08903f05d3a544f548535c222b1c205b9f5a154/processor/resourceprocessor/README.md):

+To deploy this collector, follow the steps in [Getting Started in OpenTelemetry Collector](https://opentelemetry.io/docs/collector/getting-started/).
+Several components are available in the collector, and they could be combined for different use cases.
+
+After installing the collector, you may configure it to scrape metrics from Istio and send them to SkyWalking backend.
+
+The job configuration to scrape metrics from Istio and send them to SkyWalking backend is as follows:
+
+```yaml
+receivers:
+  prometheus:
+    config:
+     scrape_configs:
+     - job_name: 'istiod-monitor'
+       kubernetes_sd_configs:
+        - role: endpoints
+       relabel_configs:
+        - source_labels: [ __meta_kubernetes_service_name, __meta_kubernetes_endpoint_port_name ]
+          action: keep
+          regex: istiod;http-monitoring
+        - action: labelmap
+          regex: __meta_kubernetes_service_label_(.+)
+        - source_labels: [ ]
+          target_label: cluster
+          replacement: your-cluster # replace this with your cluster name
+
+exporters:
+  otlp:
+    endpoint: oap.skywalking:11800 # replace this with the OAP gRPC service address
+    tls:
+      insecure: true
+
+service:
+  pipelines:
+    metrics:
+      receivers: [ prometheus ]
+      exporters: [ otlp,logging ]
 ```
 
-Note: If you try the sample Istio Prometheus Kubernetes configuration, 
-you may experience [an issue](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/4980). 
-Try to fix it using the solution described in the issue.
-
-#### OpenCensus exporter
-Follow [OpenCensus exporter configuration](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/a08903f05d3a544f548535c222b1c205b9f5a154/exporter/opencensusexporter/README.md)
-to set up a connection between OpenTelemetry Collector and OAP cluster. `endpoint` is the address of the OAP gRPC service.

 ## Observing Istio
 
 Open Istio Dashboard in SkyWaling UI by clicking `Dashboard` -> `Istio`. You can then view charts and diagrams
