The update and extract LOB commands were not adhering to USE_LIBHDFS
settings. This has been fixed in commit ee44ad9. However, all the DDL lob
functions executed via the CLI call SQL_EXEC_LOBddlInterface will not adhere to
USE_LIBHDFS settings if the CQD is set in defaults table. Instead the CQD
should be set via DCS profile till we fix the issue of transforming CQD into
SSD for the CQDs in defaults table. Because it is is DDLinterface, it should
be ok even if it couldn't switch to older implementation.

> By making LOB to use the new implementation of HdfsClient, the use of libHdfs
> is avoided in yet another feature. This also simplifies the hdfs access
> related code in this feature.
