Description

We could support some form of auto-completion for Metaflow in iPython. Some examples:

def _ipython_key_completions_(self):
    return [s.id for s in self.steps()]

on a run to complete something like my_run['<tab>

Details on the possibilities here: https://ipython.readthedocs.io/en/stable/config/integrating.html#tab-completion

Research direction
Implement ` ipython key completions ` method on the Metaflow `Run` class to enable tab completion for step IDs in IPython. Refer to the linked IPython documentation for integration details. Check existing comments for any proposed API or implementation considerations. The method should return a list of step IDs from `self.steps()`.
