> Please review this change that moves the `Remembered Set Sampling Task` from `g1ServiceThread.cpp` into `g1RemSet.cpp`. This is basically just a move but with a small edition that the task will reschedule itself instead of running if at start of execution the last GC happend more recently than the value of `G1ConcRefinementServiceIntervalMillis`.
> This change does not cover moving the timing measurements from the service thread into the task, that will be covered by: 
> [JDK-8252645](https://bugs.openjdk.java.net/browse/JDK-8252645)
> Testing
> Tier1-3 + local verification that the tast is scheduled as expected.
