    METRON-1880 Use Caffeine for Profiler Caching

    Caffeine is a more performant cache when cache sizes are larger.  We've already seen a significant improvement elsewhere in Metron based on the work done in #947. 
    
    The Profiler should use Caffeine for caching to ensure that the caches are not a performance bottleneck.
    
    ## Testing
    
    1. Spin-up Full Dev.
    1. Create a profile using the Stellar REPL.
    1. Deploy the profile for the Storm-based Profiler.
    1. Ensure valid profile data is persisted in HBase.
