Add Documentation for Monitoring

[patcher9]

Hi team, I've updated the documentation to include both Julep's built-in Prometheus metrics and how to integrate with OpenLIT for better monitoring.

I am one of the maintainers of OpenLIT and we support Obserability for LLM apps built using Julep AI, It is all OpenTelemetry-native so the traces and metrics can be sent to any platform like Grafana or any OSS OTel tools

Although I know Julep has Prometheus metrics inbuilt like various countres, OpenLIT helps when the users are using LLM + VectorDBs + Other framework actions as the consolidated monitoring gives them a complete picture.

Figured the mention here might be useful for developers using Julep hence adding the reference in documentation page.

Let me know your thoughts on this and placement for this!

Thanks for the PR, @patcher9 ! I'd love to explore integrating openlit with julep even more closely. We are Apache 2.0 licensed, does that work with you guys?

@creatorrr We love Apache 2.0! (OpenLIT is also completely Apache 2.0). And yup would love integrating with you folks!
