    I ran this up with vagrant and ensured:
    * Normal stellar works still in field transformations as well as enrichments
    * swapped in and out new enrichments live
    * swapped in and out new threat intel live

> Based on the performance tuning exercise as part of METRON-1460, guava has difficulties
with cache sizes over 10k.  We, unfortunately, are quite demanding of guava in this regard
so we should transition a few uses of guava to Caffeine:
>  * Stellar processor cache
>  * The JoinBolt cache
>  * The Enrichment Bolt Cache
