ToolBox management as FC

While the base functions for adding functions and APIs as tools work for appending new functions to an existing Python list, these functions cannot be easily transformed into tools to be used for function calling because:

• Changes must be made into the top-level tools and continue to be applied in all subsequent conversations.
• tools cannot be safely interpreted as a part of message as in some cases new tool changes may exceed token limit.

One solution to this is to introduce a special fix-up function is used for handlers which accesses the correct instance of tools. This function is to be created and attached to the tools instance at the moment of creation. However, this may cause issues on the application side as there might be multiple instances of tools being created. To combat this issue, we can have an alternative workflow involving a mapping of session_tools which maps each instance of tools with a corresponding unique ID. Paired with this mapping will be an fix-up function which extracts the tool instance and pass into core execution function.
