Explore adding an OTEL SDK shim

[jsumners-nr]

The OpenTelemetry SDK allows for the injection of its constituent parts (context manager, trace provider, metrics provider, etc.). By utilizing this feature, we should be able to add a shim to our agent that would allow us to support utilizing @opentelemetry scoped tracing packages to gain instrumentations for packages we do not support, e.g. knex.

Success for this issue entails:

1. Being able to load an OTEL tracing module (e.g. @opentelemetry/instrumentation-knex)
2. Running an app with the instrumented module
3. Seeing trace data in a New Relic dashboard

The outcome should be a statement on whether or not this is an avenue we would like to continue pursuing.
