Create `CTRL + C` signal handler for gracefully pipeline stopping

[gabrielmbmb]

Create a signal handler that captures SIGINT (ctrl + c) and stops the pipeline gracefully.

This consistently stops me from being able to stop the execution of a pipeline if or when it got stuck somewhere. Would probably be best to have some override like exiting if crtl+c was pressed more than once or twice.

To reproduce this @plaguss you can just create an infinite running step as:

import time

from distilabel.steps import StepInput, step
from distilabel.steps.typing import StepOutput

@step()
def InfiniteStep(*inputs: StepInput) -> StepOutput:
    time.sleep(100)

And the CTRL+C will be captured, but the SIGTERM signal won't be sent.

Hi @bjoernpl in the next release this should be tackled: https://github.com/argilla-io/distilabel/pull/630
