Surya Hebbar e419964250 IMPALA-13615: Support row grouping of instances based on fragment names ...

In the "Fragment Instances" page of a query, even though it is possible
to sort the rows based on the fragment's name, it is difficult to
distinguish between fragments and their instances.

With row grouping based on fragment's name, it becomes easier to
distinguish one fragment's instance from the other.

The lexographical sorting of instances can still be done based on
different columns, which splits the fragment's group and orders the rows
lexicographically only based on the column's values.

Row grouping has been implemented using the "RowGroup" extension
for datatables - https://datatables.net/extensions/rowgroup/.

Datatable libraries and its extensions have been added under the
directory - "www/datatables".

The datatable library's license has been updated according to
version 1.13.2, which was previously not updated.

The related row grouping extension's license has also been included.
