IntegrationTestImportTsv is generating HFiles under the working directory of the
current hdfs user executing the tool, before bulkloading it into HBase.
Assuming you encrypt the HBase root directory within HDFS (using HDFS
Transparent Encryption), you can bulkload HFiles only if they sit in the same
encryption zone in HDFS as the HBase root directory itself.
When IntegrationTestImportTsv is executed against a real distributed cluster
and the working directory of the current user (e.g. /user/hbase) is not in the
same encryption zone as the HBase root directory (e.g. /hbase/data) then you
will get an exception:
```
ERROR org.apache.hadoop.hbase.regionserver.HRegion: There was a partial failure
due to IO when attempting to load d :

IntegrationTestImportTsv/hfiles/d/74655e3f8da142cb94bc31b64f0475cc
can't be moved into an encryption zone.
```
In this commit I make it configurable where the IntegrationTestImportTsv
generates the HFiles.
