RFR: 8302883: JFR: Improve periodic events

Mon Feb 20 16:44:49 UTC 2023

Could I have a review of an enhancement that addresses shortcomings of the RequestEngine class when it comes to maintainability, thread safety, scalability and predictability. See bug for details.

Testing:
100 * jdk/jdk/jfr
Manual inspection of periodic events to make sure they are emitted as expected.

Thanks
Erik
