Luiz Gavioli 67391f1f0f NetApp: Add use-exact-size parameter when creating a LUN on ONTAP iSCSI
When a cinder volume is created the ontap backend fits the LUN to the
best geometry. It makes the image uploaded from a volume larger than
expected and a volume of larger size must be created from that image.
Using the use-exact-size parameter the backend does not fit to best
geometry, the image uploaded from that volume has the same size and a
volume of the same size may be created from that image.

Nevertheless this parameter is available only in Data ONTAP 9.1 (ontapi
version 1.110) and later.

Fixed bug #1731474 on NetApp Data ONTAP driver that was causing LUNs to be created
with larger size than requested. This fix requires version 9.1 of ONTAP
or later.
