Be more explicit about the scope of gnt-cluster upgrade

Add an explicit statement to the documentation that gnt-cluster upgrade
only handles the switching between Ganeti versions, not the installation
or removal of the Ganeti binaries. Some users got confused about this.

......@@ -28,6 +28,16 @@ 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.
Note that ``gnt-cluster upgrade`` only manages the actual switch between
versions as described below on upgrades from 2.1 and above. It does not install
or remove any binaries. Having the new binaries installed is a prerequisite of
calling ``gnt-cluster upgrade`` (and the command will abort if the prerequisite
is not met). The old binaries can be used to downgrade back to the previous
version; once the system administrator decides that going back to the old
version is not needed any more, they can be removed. Addition and removal of
the Ganeti binaries should happen in the same way as for all other binaries on
your system.
