Granular rate limits

[dingo-d]

Description

This PR is a port of #498 to v8 of the forms plugin. As mentioned in the original PR:

This PR largely refactors the entire Security namespace, and adds support for granular rate limits (per form), in addition to global rate limits.

TL;DR:

• adds a new database table for rate limits
• uses it in the Security class
• adds a post meta to forms for granular rate limiting
• adds a model for log entries
• adds a cleanup service which tries to use Action Scheduler if available or just cleans up if not

Note: I started cleaning up the tests, but I think the automated tests should be refactored, as I keep getting failures like:

   WARN  Your XML configuration validates against a deprecated schema. Migrate your XML configuration using "--migrate-configuration"!

Forms also now have this: #522

Not sure how do these two compare.

Activity log shouldn't be the same as this. At least by the name 🤷🏼‍♂️

tnx for the PR, I will try to merge this to the next release and see if there are any additional changes necessary.
For test, don't bother they are not working at all. We will fix them in the future release
