[8u] [JFR] RFR: JFR backports from 11.0.4

[Mario Torre]

Awesome, thanks for checking zero.

As discussed offline, we have a few backports that were directly
backported to 8u without first being in 11u:

https://bugs.openjdk.java.net/browse/JDK-8185525
https://bugs.openjdk.java.net/browse/JDK-8223599
https://bugs.openjdk.java.net/browse/JDK-8225310
https://bugs.openjdk.java.net/browse/JDK-8221711
https://bugs.openjdk.java.net/browse/JDK-8222888
https://bugs.openjdk.java.net/browse/JDK-8216283
https://bugs.openjdk.java.net/browse/JDK-8220555
https://bugs.openjdk.java.net/browse/JDK-8217362
https://bugs.openjdk.java.net/browse/JDK-8221569
https://bugs.openjdk.java.net/browse/JDK-8224217

A couple of those are wither being worked on or of interest for 11u,
so they should be fine, some aren't and while may not be critical I
think they are nice to have (like the container tests), so I would
expect all of them to be backported to 11u.

Since this is a staging repository we may go ahead and push them and
work on the backport to 11 afterward, but I would prefer to not create
a discrepancy at this moment, so if possible we should work on the
backports to 11 first.

Cheers,
Mario
