Use Core Flood Service for hard blocking users?

Problem/Motivation

Hard blocking implemented by this module seems to be very similar to what Drupal Core 8+ does with its flood service.

I guess that when this module was developed for Drupal 7, that didn't exist.
See https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Flood%21F...

So we should discuss how to better integrate with Core's flood functionality and extend it with this modules helpful functionality like notifications, settings, etc. for hard blocking.

Edit: I just saw, that the module already has a dependency on drupal:ban module, so perhaps parts of this already use the core flood functionality. This has to be researched.

Steps to reproduce

Set a login_security limit that's lower than the one from Core Flood and see that not

Proposed resolution

1. Find and write down differences here
2. Make a plan for integration and discuss it
3. Implement
4. Test
5. Release

That may for example include:

• Remove duplicate functionality from this module and instead refer to flood_control for settings and unblocking
• If possible, extend the core flood functionality
• Ensure that additional functionality like messages, soft-blocking and other features are preserved

Remaining tasks

User interface changes

API changes

Data model changes
