Mention gnt-cluster upgrade in UPGRADE

Ganeti 2.11 is the first version of Ganeti reachable (from 2.10) with
gnt-cluster upgrade. Hence suggest this method in the UPGRADE notes.

--------------
Starting from 2.10 onwards, Ganeti has support for parallely installed versions
and automated upgrades. The default configuration for 2.11 and higher already is
to install as a parallel version without changing the running version. If both
versions, the installed one and the one to upgrade to, are 2.10 or higher, the
actual switch of the live version can be carried out by the following command
on the master node.::
$ gnt-cluster upgrade --to 2.11
This will carry out the steps described below in the section on upgrades from
2.1 and above. Downgrades to the previous minor version can be done in the same
way, specifiying the smaller version on the ``--to`` argument.
