Fixing command line interface for the run command.

This commit fixes bugs associated with the MLCube's `run` command:
- It now uses correct option decorators from the `cli` (class Options) instead of deprecated decorators from the `__main__.py` file.
- It now uses the `-P` option to correctly parse MLCube parameters that users provide on a command line.

The latter particularly fixes the mlcommons#347 issue.
