cm-cli.py :specify commit ID /tag or branch when installing nodes and add 'exit-on-fail' parameter to control failure behavior

[VitoChenLY]

• Details:

• The @@ delimiter allows users to specify a specific commit ID, tag, or branch for the node installation.

• This feature enhances flexibility by enabling users to install nodes from specific versions of a repository.

• Add 'exit-on-fail' parameter to control failure behavior

• Example:

• Install a node from a specific branch:

  python3 cm-cli.py install [email protected]:evanspearman/ComfyMath.git@@main
  

• Install a node from a specific tag:

  python3 cm-cli.py install https://github.com/Nourepide/ComfyUI-Allor.git@@v1.0.0
  

• Install a node from a specific commit ID:

  python3 cm-cli.py install [email protected]:evanspearman/ComfyMath.git@@2ee689
  

• The exit_on_fail parameter determines whether the process should exit when an action fails.

   python3 cm-cli.py install --exit-on-fail [email protected]:evanspearman/ComfyMath.git@@rag https://github.com/Nourepide/ComfyUI-Allor.git@@2ee689
  

• Impact:
  This change improves the usability of the cm-cli.py script by allowing users to install nodes from specific versions of repositories, rather than always using the default branch. Parameter '--exit-on-fail' enhances the flexibility of the cm-cli.py by allowing users to control the behavior when an action fails, without forcing an immediate exit.

Please base the feature implementation on feat/cnr branch.
The structure of the main branch will change completely once feat/cnr is merged, so avoid adding new features to main as much as possible.
