* Update Readme to match expected behavior for JdbcCreateTable
* Update sample properties file to use correct property key

Tried to simplify the distinction between using JDBC's addBatch()/executeBatch()
API calls and "batching" updates via autoCommit=false and a manual commit() after
a given number of updates.

Breaks out flavors into their own package to reduce bloat in JdbcDBClient.

Encompasses changes from Enis Soztutar.

Add Phoenix flavor for Apache Phoenix.

Changes to account for the field ordering. Now correctly inserting and
updating field values so that they can be verified when using
dataintegrity=true.

Fixes #132

* Cleaned up javadoc and comments
* Backed out unnecessary line breaks
* Updated license

Closes #494

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.

        mvn org.apache.rat:apache-rat-plugin:0.11:check -D rat.numUnapprovedLicenses=5000

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

This will ensure record ordering my the primary key.

Now properly enforcing a scan of the given number of documents in the
scan operation using the LIMIT modifier in the cached statement.

Fixes #171.

Fixes #438

JDBC scans did not instruct the driver to use a specific fetchsize,
resulting in most cases in an OOM; add support for setting fetchsize.

Also add support for disabling autocommit on the JDBC connections,
mostly because Postgres for example doesn't support setting fetchsize
without disabling autocommit.
