Kevin Carter 6017fc0e89 Add the ability to set the JVM heap size
This change makes it possible for users to set the `elastic_heap_size_default`
value. Before this change, the option was unreachable due to a series of facts
ganerated template values. The options `elastic_heap_size` or `logstash_heap_size`
have also been exposed giving deployers the ability to define service specific
heap sizes as needed.
