    The AccessTracker allows us to track which keys in the hbase table are accessed.  This
is so that pruning an be done based on most current usage.  It is used in the exisiting HBase
Enrichment/ThreatIntel bolt, so it's being continued to be used here.  There are two access
trackers currently setup, one is a noop, which is the default.  The other one is to capture
the key being accessed in a bloom filter and write the filter out to HBase periodically. 
The `threatintel_bulk_pruner.sh` uses this table for pruning infrequently used rows.
