Mission Control - Ability to specify alternate home directly location during install

During Mission Control installation ElasticSearch and MongoDB home directories default to /var/lib/[product_name].  To prevent /var from filling up, we would like the ability to specific alternate home directory locations for ElasticSearch and MongoDB during the Mission Control process or post-install via a config. file (update file, stop appl, move date to new location, restart appl), or both.
