Allow the ability to customize which tools a task generates

[jlowin]

Enhancement Description

Currently tasks generate succeed/fail tools for all agents (or all completion agents). In some cases, it may be advantageous to only generate a success tool, or no tools!

For example:

• showing agents a failure case may result in worse performance
• you want to manually give tools to agents e.g. by calling create_success_tool() yourself, so you want to disable automatic tool generation completely

CF should:

• make each task's tool generation behavior configurable
• allow setting this at the flow level
• allow setting this globally

Use Case

Proposed Implementation

cf.Task(..., completion_tools=['succeed', 'fail'])
