Documentation should specify Java requirements for Hadoop

[exalate-issue-sync]

Documentation should state what Java versions are supported when running H2O on Hadoop.

The reference point is Hadoop itself (it doesn't make sense to support versions that Hadoop itself doesn't support). From [https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+Java+Versions|https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+Java+Versions]

• Hadoop only supports Java 8 and Java 11

Our documentation should recommend running H2O only on Java 8 and Java 11 (this is the versions we test).

This is related to [https://h2oai.atlassian.net/browse/PUBDEV-8341|https://h2oai.atlassian.net/browse/PUBDEV-8341|smart-link] - we should make a clear distinction what we support in standalone/k8s and on Hadoop.
