Feature summary

move to LLM gateway - instead of directly managing LLM configs via langchain

Feature description

use LLM gateway - selfhosted docker image. make Lang chain to use open router for LLM access.

initially felt open router, but after evaluation it didn't sound like a good fit.

After a bit of research Portkey gateway seems to be a good fit.
