gh-95 Update the MongoDB driver to use a singleton Mongo instance for
each test client.

Add a control (via properties) for the number of connections the Mongo
instance will create/use.
gh-95 Update the MongoDB driver version to 2.9.0.
gh-102 Minor fix so the classpath path separator is OS independent
gh-100 Time clean up and count it for hbase as update.

* Time the cleanUp of a DBWrapper
* For HBase this clean up should also be counted as an update.
gh-47 Fix an issue with JDBC scans

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.
