Opentelemetry-Openseacrh integration example

This is a "simple" example of an integration between opentelemetry and opensearch. The ideia behind this example is to:

use Otel SDK and API to generate traces and metrics data
export trace data to Otel Collector
export data from Otel Collector to Opensearch Dataprepper
export data from Dataprepper to Opensearch
visualize trace and metric data with Opensearch Dashboards
