Instrument with swift-distributed-tracing, and otel-tracer to report into aws-otel

AWS launched https://aws-otel.github.io

so they have a collector available now that accepts otel.

We have the following pieces ready:

- https://github.com/apple/swift-distributed-tracing
- an minimal otel Tracer compatible with the above APIs https://github.com/slashmo/opentelemetry-swift

Otel just hit 1.0 recently as well.

by using these to revive the instrumentation effort of lambda here things work well.

We should:

- bump dist-tracing otel support to 1.0 and tag it
- instrument lambda
- perhaps import or use the otel tracer in here
- consider going through sswg first
