[hbase] update HBase bindings for eom (#1396)

* remove 0.98, 1.0, 1.2, and 2.0 bindings
* change the 1.4 binding to be  a "HBase 1.y" binding
* add "HBase 2.y" binding and default it to the current 2.2 release
* incorporate README from 0.98 binding into current bindings
* incorporate README on bigtable testing from 1.0 binding into 1.4 binding
* incorporate implementation from 1.0 client into current bindings
* updated asynchbase binding to include parts of removed bindings it referenced
* update maprdb binding for the change in the hbase bindings
* update 1.4 and 2.2 to current releases
* use shaded client test for all hbase bindings.
* make hbase bindings consistently use log4j
* fixes #1173
* fixes #1172

 ## Quickstart
 
-### 1. Setup Hbase
+### 1. Start a HBase Server
+You need to start a single node or a cluster to point the client at. Please see [Apache HBase Reference Guide](http://hbase.apache.org/book.html) for more details and instructions.
+
+### 2. Set up YCSB
+
+Download the [latest YCSB](https://github.com/brianfrankcooper/YCSB/releases/latest) file. Follow the instructions.
+
+### 3. Create a HBase table for testing
+
+For best results, use the pre-splitting strategy recommended in [HBASE-4163](https://issues.apache.org/jira/browse/HBASE-4163):
+
+```
+hbase(main):001:0> n_splits = 200 # HBase recommends (10 * number of regionservers)
+hbase(main):002:0> create 'usertable', 'family', {SPLITS => (1..n_splits).map {|i| "user#{1000+i*(9999-1000)/n_splits}"}}
+```
+
+*Failing to do so will cause all writes to initially target a single region server*.
 
-Follow directions 1 to 3 from ``hbase098``'s readme.
 
 ### 2. Load a Workload

 * `durable`: When set to false, writes and deletes bypass the WAL for quicker responses. Default is true.
 * `jointimeout`: A timeout value, in milliseconds, for waiting on operations synchronously before an error is thrown.
 * `prefetchmeta`: Whether or not to read meta for all regions in the table and connect to the proper region servers before starting operations. Defaults to false.
