[one-users] contribution of LVM2 transfer manager driver for opennebula 3.4.x

[Ruben S. Montero]

Hi,

As Rolandas said, there should not be any problem running the drivers in
3.6. OpenNebula 3.6, includes LVM TM [1] contributed by Nicolas AGIUS.  If
there is any missing feature in the current ones, let us know.

Cheers

Ruben
