Create std_function for LLM Confirmation

[josecomartins]

Create std_function for LLM Confirmation including:

• std_functions
• interfaces

Main changes:

The Interfaces need to return [string:talk, string:task, bool:confirm]

This issue doesn't include the LLM package

I'm changing that on this branch #72

The Interfaces need to return [string:talk, string:task, bool:confirm] - INCORRECT

After our meeting we decided that the bool to confirm is on the std_function and not on the llm node

The Interfaces need to return [string:talk, string:task] - CORRECT
