Optimizing Connection - (a) minimize fencing by using thread local
protocol handlers.
Retried/Depracted Connectors:
1 - Problem child JRedisService is retired for posterity. Use a
connection
pool of JRedisClients instead. (May add this later; for now, roll your
own).
2 - JRedisPipelineService is (for now) also retired. Need to think a
bit about this.
Tested.
