Support for null valued columns in hadoop cql3 CqlRecordWriter.
With this patch you can insert/update null values to cql3 table in hadoop
job.
Usage:
```java
CqlConfigHelper.setOutputCql(job.getConfiguration(), "UPDATE
outputTableName");
job.getConfiguration().setStrings("cassandra.output.cqlColumns", new
String[] {"column1", "column2", ...});
```
There is also an option ```cassandra.output.skipNullColumns```. When it is
set to ```true```, null valued columns are not inserted into table (they are
simply skipped).
WARNING: This patch is not fully compatible with original version, because
columns are no longer specified in CQL statement, but they must be specified in
separate parameter ```cassandra.output.cqlColumns```.
