CLI for Tool Repository (#1357)

This commit adds two commands to the CLI:

- `crewai tool publish`
    - Builds the project using Poetry
    - Uploads the tarball to CrewAI's tool repository

- `crewai tool install my-tool`
    - Adds my-tool's index to Poetry and its credentials
    - Installs my-tool from the custom index
