fix formatting issues showing in the re-writing batched insert `db.url` example box

* [jdbc] support JDBC option to rewrite batch statement to multi-row insert

batch statement int[] results = insertStatement.executeBatch() returns 1 for successful completion. when the batch statement is re-written to multi-row insert, SUCCESS_NO_INFO (-2) is returned instead. This change expands allowable results values to be 1 AND -2

* [jdbc] note on rewriting batch insert to multi-row

This commit reverts some unrelated changes to POMs for other bindings,
perhaps made inadvertently while merging master into a development
branch.

* Update Readme to match expected behavior for JdbcCreateTable

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.

[cassandra cassandra2 dynamodb hbase098 hbase10 jdbc s3] Fixing squid:S1481 - Unused local variables should be removed

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.
