allure2: Timings Incorrect and Embedded Attachments not present when using Cucumber 4.x

What is the current behavior?

Since Cucumber 4.x events consumed by the Allure formatter plugin are not received until after the test run.

This results in the step timings showing values of 0ms and means that embedded attachments are orphaned. I believe this is because filters like like allure-rest-assured rely on the currently executing step being set in the formatter plugin.

It is possible to use a formatter that implements the ConcurrentEventListener interface; however it may not be possible to determine the currently executing step for that thread.

I have raised a related github issue on cucumber here to add this info in the events. In doing this it may also be possible to match these up after the run in conjunction with the timestamps. https://github.com/cucumber/cucumber-jvm/issues/1491

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

Will try to uplaod a demo at some point his evening.

What is the expected behavior?

Attachment should be embedded in steps. Test timings should reflect actual execution times.

What is the motivation / use case for changing the behavior?

Want to use Cucmber 4.x parallel with Allure + Embedded attachments

Please tell us about your environment:

Allure version	2.7.0
Allure-Restassured	2.7.0
Cucumber	4.0 - 4.10
