Add default name for a pipeline

[plaguss]

Description

Generate a random name for the pipeline if one is not given by default, to simplify cognitive load:

from distilabel.pipeline import Pipeline

with Pipeline() as pipeline:
    print(pipeline.name)

A name like the pipeline_33prTGVu will appear by default from now on, unless the name is given.

@plaguss is this included for Steps and LLMs too? I think we could include it there too and perhaps generalize something to f"{step_name}-{step_number}-{uuid}"?

[plaguss]

Hi @davidberenstein1957, the LLMs don't need it, the steps already have it implemented

[davidberenstein1957]

@plaguss perhaps we should update and simplify the docs where needed?

[plaguss]

Yes totally, there are some updates in #812 to the quickstart for example that should contain this (it should be here, but they are a bit mixed). Maybe we should review the docs after these 2 PRs are merged and see what to improve? Thanks for the review 🤗
