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
