if user has gptext installed along side GPDB they could oversubscribe their virtual memory very quickly Adding these form fields ensures user will account for gptext SOLR processes memory usage.

(# nodes/Solr processes created) X (max JVM set aside for each process)
For example, if there are 4 nodes on each host and the JVM settings are "-Xms1024M -Xmx2048M", it would use:
4 nodes * 2GB/node = 8 GB set aside on each host.
