[BUZZOK-26844] Remove drum server from everywhere in genai_agents image, replace with drum inline predictor

[mjnitz02]

This repository is public. Do not put here any private DataRobot or customer's data: code, datasets, model artifacts, .etc.

Summary

This removes the use of the DRUM Server from everywhere in run_agent. Instead we are now using the drum_inline_predictor which is a python process that runs in memory without requiring any extra services or threads to be spun up.

This is:

• Faster to start
• More efficient and uses no extra ports
• Shows the errors properly in all failure conditions
• Easier to debug and maintain
