c68478f470 Customize LLM config per agent (#2756)
Currently, OpenDevin uses a global singleton LLM config and a global singleton agent config. This PR allows customers to configure an LLM config for each agent. A hypothetically useful scenario is to use a cheaper LLM for repo exploration / code search, and a more powerful LLM to actually do the problem solving (CodeActAgent).

Partially solves #2075 (web GUI improvement is not the goal of this PR)

9b371b1b5f Refactor agent delegation and tweak micro agents (#1910)
This PR fixes #1897. In addition, this PR fixes and tweaks a few micro-agents.

For the first time, I am able to use ManagerAgent to complete test_write_simple_script and test_edits tasks in integration tests, so this PR also adds ManagerAgent as part of integration tests. test_write_simple_script involves delegation to CoderAgent while test_edits involves delegation to TypoFixerAgent.

Also for the first time, I am able to use DelegateAgent to complete test_write_simple_script and test_edits tasks in integration tests, so this PR also adds DelegateAgent as part of integration tests. It involves delegation to StudyRepoForTaskAgent, CoderAgent and VerifierAgent.

This PR is a blocker for #1735 and likely #1945.
