Add new command 'inspect model'

[gayanW]

This adds new command launchable inspect model.
This should only be merged after https://github.com/launchableinc/mothership/pull/12415

Usage:

% launchable inspect model
| Metadata                        |   Value |
|---------------------------------|---------|
| Training Cutoff Test Session ID |     256 |

% launchable inspect model --json
{
  "training_cutoff_test_session_id": 256
}

Could training_cutoff_test_session_id be null? If not, it's okay; otherwise, this throws KeyError, which is not our expectation.

[gayanW]

It can't be null because the API returns 404 if the value is null in the DB.

What will happen if the subset is not enabled in the workspace? In other words, what error message will be displayed if the subset is not allows in the workspace?

I just tested. The /model-metadata endpoint only queries the models table. So it's not affected by the data in the workspace_feature_flags table. If DB entry for that workspace not found, or if the the value of the training_cutoff_test_session_id column is null, it returns 404. So in that case CLI would output:

"Model metadata currently not available for this workspace."
