Manage watchfiles settings

[q0w]

I've replaced autoreload.get_reloader with autoreload.run_with_reloader to get verbosity level to setup debug mode. Other settings you can get from the project settings WATCHFILES, e.g.:

WATCHFILES = {
    'watch_filter': 'path.to.custom_filter',
    'raise_interrupt': False,
    'debug': False,
}

I've updated pre-commit hooks since black 22.1.0 was broken

@adamchainz This looks like a solid contribution. Does this align with your vision for the project?

Very much thumbs up for this 👍

It's practically unusable for me without this patch. I get like an endless amount of debug output even when I haven't changed a file. We started using this at work and my colleagues doesn't experience the same problem as me though.

Great contribution! Looking forward to release. IMO this is the key part missing to give django-watchfiles a decent developer experience.

@adamchainz Could you please take a look at this PR and give your feedback? It's been open for a year now and is a blocker for me and other people to adopt django-watchfiles. Thank you!

If changes were reverted from the .pre-commit-config.yaml would that help with getting this merged in? I would be happy to help or submit a second PR with reduced scope if that would be useful. @adamchainz @flbraun
