[S3] added S3 storage binding

Closes #413 

[elasticsearch] Checkstyle updates for Elasticsearch.

[redis] Checkstyle updates for the Redis binding.

[voldemort] Update binding to use the new Status class and also checkstyle updates.

[core] passing full fieldset for verification

When dataintegrity and readallfields are both true, pass the full field
set to db.read() so that the field values can be verified.

Fixes #496

[core] added return codes to VERIFY

[jdbc] removed semicolons from cached statements

Changed measurement latency to actual latency time of the verifyRow step
and now recording Status codes for verify operations.

Fixes #479

[kudu] Checkstyle updates for the Kudu binding.

[hbase10] Checkstyle updates for HBase 1.0 binding.

checkstyle updates.

Closes #477. This is #477 rebased against current master, with long
lines in commit messages wrapped.

Extend the dynamoDB client to support the HASH_AND_RANGE primary key
type. The default primary key type remains exactly the same as before:
HASH type. And the default behavior and processing logic also remains
exactly the same as before.

What's added is the support to benchmark a primary key type called
HASH_AND_RANGE which is one of two supported primary key types of
DynamoDB. Knowing the performance characteristics of the HASH_AND_RANGE
key is important for some users because that's the only practical way
for them to get strongly consistent query across multiple items.

See documentation in conf/dynamodb.properties for more details.

JDBC test cases

reverted a few things that were not necessary
* semicolon change - coming in another PR
* .gitignore change - no longer using derby

Code cleanup
* test scoped hsqldb
* removed derby artifacts and references
* setting driver class is not necessary
* cleaned up unused objects in delete
* now running cleanup on client
* removed old assert(true) stub

Had to fix the semicolon issue for Derby.
Ended up switching to HSQLDB becuase Derby does not support LIMIT.

Also fix a few README formatting issues.

[core] Fix the build post the #461 merge.

Add a new and optional measurement type called "RAW" which outputs every dat apoint of a run.

Add single definition of status codes

[jdbc] JDBC module fields fix

1. Use LinkedList rather than ArrayList for the measurement array in RAW. Update size estimation in documentation in workload_template.

2. Add a new composite measurement type which combines HdrHistogram and RAW.

3. Allow user to optionally disable output of summary stats from the raw measurement class.

Replaces numeric status codes with a canonical set of Status objects,
each with a short name and description.
Bindings with more specific errors (e.g., timeouts) return additional
statuses.

This changes the default output from messages like:

   [UPDATE], Return=0, 511

To:

   [UPDATE], Return=OK, 511

[jdbc] added LIMIT to JDBC scan operation
