OpenTelemetry is a collection of tools, APIs, and SDKs. You can use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) for analysis in order to understand your software's performance and behavior. I think it's time to integrate the EventMesh with it now since OpenTracing and OpenCensus have been integrated into one. In this summer, you are supposed to finish the following tasks:

1. Finish the OpenTelemetry instrument with EventMesh Java SDK.
2. Finish the OpenTelemetry EventMesh Connector, let it export the data to EventMesh and receive data from EventMesh.
