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
