Performance testing query server

[moradology]

When comparing GM/GW performance roughly one year ago, the GeoTrellis team produced some tooling for testing the performance of queries against accumulo and hbase stores. We should reuse some of that effort here to get a sense of query performance in the relatively exotic hbase on top of s3 architecture we're pursuing

A heads up that there is a decent looking tuning guide for performance here under the Properties for HBase on Amazon S3 Performance Tuning section.
