🚀 Feature: re-write LlamaIndex instrumentation to use LlamaIndex `CallbackManager` about openllmetry-js

[kartikay-bagla]

Yeah, I'll get started on this because I think it'll take some time.

Small update, with this being a larger code change than expected, and some unscheduled life things, I might have to put this on hold until the 18th. Will keep you updated though.

@nirga I was looking at the LlamaDebugHandler (in the python code) and it looks like in terms of features, I just need to recreate this and extend it to add the existing traces. Does that sound correct?

[nirga]

Yep @kartikay-bagla. It's a bit trickier cause you need to create and close spans accordingly, and make sure to nest them correctly.

[kartikay-bagla]

So I was able to make some progress over the weekend, but it is slow as I couldn't find any existing implementation of callback_manager that I could use as a starting point.

Thanks so much @kartikay-bagla! I've been in touch with the folks at LlamaIndex so ping me here or on slack if you have any questions I can pass along.
