New component: Zipkin V2 UDP Receiver

[EOjeah]

The purpose and use-cases of the new component

This component will enable the Collector to receive traces in the form of Zipkin v2 JSON spans over UDP.

Example configuration for the component

zipkin_udp:
  listen_address: ":52352"
  udp:
    queue_size: 1000
    num_workers: 10
    buffer_size: 100
    max_packet_size: 65000

Telemetry data types supported

traces

Is this a vendor-specific component?

• This is a vendor-specific component
• If this is a vendor-specific component, I am a member of the OpenTelemetry organization.
• If this is a vendor-specific component, I am proposing to contribute and support it as a representative of the vendor.

Additional context

Currently, the OpenTelemetry Collector supports receiving Zipkin traces over HTTP. However, some environments with very high throughput use case can benefit from the lower overhead and simplicity of UDP.

Due to nature of UDP as inherently unreliable, packets may be lost but the risk is mitigated by the nature of tracing data, where occasional loss of spans is generally acceptable.
