Autolabel config cli

[Tyrest]

Adds an Autolabel CLI to reduce friction for new users! #456

Here's what a sample use case might look like for the company dataset

First execute the create-config command...

Then, execute plan to make sure everything looks good...

Finally, execute run to start the labeling task!

New Automatic Config Creation

The goal for this is to have the user do as little as possible to get to a working config.

New Help Page for Config Command

Changes from the meeting w/ @Tyrest @rajasbansal :

Autolabel config:

1. "wizard" mode is the default -- it is an interactive multi-step workflow to arrive at a final config
2. "non wizard" mode will be invoked with "autolabel config init". It outputs a template/starter config with all the valid keys, and values being descriptions of what value should the user put there. E.g.:

{
    "task_name": "[TODO] Enter task name",
    "task_type": "...",
    "dataset": {
        "label_column": "...",
        "delimiter": "..."
    },
    "model": {...},
    "prompt": {...}
}

Added placeholder values for values that we cannot infer as shown below.

The new default for autolabel config is the wizard:

lgtm!
do we need to add any dependencies for the CLI app ?
