Create tool YAML and list that can be populated from a tools catalog

[maximilien]

As part of the work to test a meta-agent that can generate agents and workflows based on textual description. We hypothesize that access to a list of tools will be necessary since this could allow not only enhancing existing agents with tools for react-style agents but also ability for meta-agent to know what is missing or available to implement the workflow. This is related to issue #259.

Suggesting the following tasks:

• define tool YAML. Should follow existing YAML structure but also at minimum add: input and output schema for the tool and link or code for tool
• create JSON schema for tool
• include tool schema validation in current CI for schema validations
• test tool schema by manually creating a list from existing tools, e.g., BeeAI tools, CrewAI, and other tool repositories
• modify existing demos to ensure the react agents there use the tools in list
• test ability for meta-agent to use tool list

Should also have ability to handle/create custom tools if possible, since for more complicated demos this is what primarily will be used
