feat: OTEL wiring in grpcserver interceptor (DataDog POC) (backport #612)

[mergify]

This PR wires up OTEL tracing in gprcserver interceptor, allowing tracing requests that originate from external services.

I had to bump up go as 1.20 did not support some of the otel grpc dependencies.

This has led to bumping up go versions of a lot of the CI stuff.

Tested.
