Should get_openai_callback move from langchain-community to langchain-openai as this is more tightly associated with openai

Checked

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

I want to understand if get_openai_callback can be moved to langchain-openai to ensure all openai related implemention in same place. If not wanted to understand the design choice

Motivation

I am trying to reduce the number of direct dependency and I have to bring community and related packages just for the usage of get_openai_callback. Trying to see if it can be avoided.

Proposal (If applicable)

get_openai_callback can be moved to langchain-openai
