istio向otel-collector上报trancing数据

1.通过OpenTelemetryTracingProvider的方式

参考：https://istio.io/latest/zh/docs/reference/config/istio.mesh.v1alpha1/#MeshConfig-ExtensionProvider-OpenTelemetryTracingProvider

 

2.通过proxyconfig的方式

参考：https://istio.io/v1.19/docs/reference/config/istio.mesh.v1alpha1/#ProxyConfig

           https://istio.io/v1.19/docs/reference/config/istio.mesh.v1alpha1/#Tracing

           https://istio.io/v1.19/docs/reference/config/istio.mesh.v1alpha1/#Tracing-OpenCensusAgent

 

otel-collector开启55678端口，proxyconfig配置opencensusagent

注意，这种方式在后面的版本被废弃了
