HBASE-20264 add Javas 9 and 10 to the prerequisites table and add a note about using LTS releases. 

* Make the #java anchor point at a section instead of directly at a table
* Add a note to the intro of that section about LTS JDKs
* Add columns for JDK9 and JDK10 that say unsupported and point to HBASE-20264

The following table summarizes the recommendation of the HBase community wrt deploying on various Java versions. An entry of "yes" is meant to indicate a base level of testing and willingness to help diagnose and address issues you might run into. Similarly, an entry of "no" or "Not Supported" generally means that should you run into an issue the community is likely to ask you to change the Java environment before proceeding to help. In some cases, specific guidance on limitations (e.g. wether compiling / unit tests work, specific operational issues, etc) will also be noted.
.Long Term Support JDKs are recommended
[TIP]
====
HBase recommends downstream users rely on JDK releases that are marked as Long Term Supported (LTS) either from the OpenJDK project or vendors. As of March 2018 that means Java 8 is the only applicable version and that the next likely version to see testing will be Java 11 near Q3 2018.
