ENT-6893: First cut of telemetry integration. (#7247)

Browse Source 
First cut of telemetry integration.

Open telemetry can be enabled in two ways, first is via an opentelemetry java agent specified on the command line. With this way you get the advantage of spans created from other libraries, like hibernate. The java agent does byte code rewriting to insert spans.
The second way is with the open telemetry driver (that links with the opentelemetry sdk). This is a fat jar provided with this project and needs to go into the node drivers directory.
