Activate sparse copy for Netapp

Activating sparse copy of files since using
"volume migration" or "retype" the size of the resulting
file is larger than before. Due to the reason that the
sparse blocks in the file are copied over completely. This
is inefficient performance wise and wastes space on the
storage itself.

Closes bug: #1534649
