Subject: [PATCH] HBASE-24007 Get `-PrunLargeTests` passing on JDK11

Minor tweaks required to get passing runs of `-PrunLargeTests`.
* Minimum Hadoop version is 3.2.0 due to
  [HADOOP-12760](https://issues.apache.org/jira/browse/HADOOP-12760).
* JDK11 looks like it consumes more memory than JDK8, so failures due
  to OOME see more common here. Bumping heap allocated to surefire
  forks allows better pass rate.
