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
> Replace guava caches in places where the keyspace might be large

> Key: METRON-1467
> URL: https://issues.apache.org/jira/browse/METRON-1467
> Project: Metron
> Issue Type: Improvement
> Reporter: Casey Stella
> Priority: Major
>
> 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
