fix: ability for consumer app to create the tracing and otel instance in the app

[gk-kindred]

Currently the library tries to setup the tracing and otel instance for the app.

• This is a bad practise tying the consumer of the app to strictly coupled with what the replicator library code is providing
• Also this makes it hard for the app using this library to get any otel tracing for any part of the code outside the library.
