Add Multi-tenancy (support multiple agencies) (#2)

- Refactor **main.py** and **agency_manager.py** to support config persistence (given correct agency_id) and multi-tenancy (can handle multiple configs);
- Refactor **config.py** to support abstract config loading and saving by agency_id;
-  Add tools: 
  - built-in: CodeInterpreter, Retrieval (not tested yet);
  - custom: BuildDirectoryTree, PrintAllFilesInDirectory + add tests.
- Remove Frontend code from this repo (will be in a separate repo).
