Refactoring code related to MLCube CLI options.
Browse files Browse the repository at this point in the history 
- Removing deprecated option definitions from `__main__.py` (new options are defined in `Options` class).
- Moving new option definitions (network, security etc.) to `Options` class.
- Removing unused and incorrect code related to parsing options accepting multiple values from the `__main__.py` file since this functionality is implemented in `cli` module.
