Fabric8 Insight indexes filling up filesystem

Issue

• It seems that the indexes that Insight in generating are filling up the file system and are not being removed.
• This is causing the filesystem to fill up and is impacting the other containers (i.e. AMQ brokers, Camel integration, etc.) in a negative way. It is our understanding that these indexes are supposed to be removed once they are delivered to the Insight data node.
• The behavior is repeated after the Insight profiles have been applied to a container for a period of time. That period of time seems to depend on how much logging it taking place in the indexes.
