HPCC-10961 Add new parameter to DFU server called "quotedTerminator"
to improve speed of CSV files spray.

Add a Boolean "quotedTerminator" parameter to spray CSV files.

If this parameter is false then we can use quick partitioning algorithm
to spray file with record structure exploration.

The default value is true.
