TASK: Removes EventLog and history module

[markusguenther]

Remove the legacy history module and event log due to incompatibility with NeosCMS 9.0's Event Sourced Content Repository. Future enhancements will be based on event-driven features.

Upgrade instructions

You can remove the setting for the eventLog in your project, but it does not harm if you keep it.

Review instructions

Check if the eventLog stuff and the history module is gone and nothing is broken.

Resolves: #4553

+1 by reading, thanks for taking care!

Unit tests failed... but need to check if it comes from my change 🙈

It seems that the failing test from the RedisBackend is not from my changes. I also have it for 9.0 branch locally.

looks great so far ;)

i think we should remove the old doctrine migrations so we dont have the neos_neos_eventlog_domain_model_event table anymore no?
