Background info:
Open Search offers a tracing solution called trace analytics. We would like to support this feature for the Open Search Plugin in Grafana, in a way we similarly do for the X-Ray datasource, where users could see traces from their open search datasource within grafana and view them using tracing visualizations.

Task List:

• Create test trace data and ingest it into a test instance of Open Search in aws #105
• Add support to view a particular trace from open search in a trace view #106
• Add an option to view multiple traces from open search in a table #107
• Make TraceIds in Trace List View Clickable and link out to individual trace views
• Trace Analytics: Traces Query and Lucene Query String #124
• Document how to use Trace Analytics features in the plugin #130
• Bug Bash
• Release
