Code Issues Proposed changes

Correct misleading documentation about upgrade levels.

Browse Source 
Documentation suggest that upgrade level shoud be locked
to new version of service (X+1) while this option
is designed to be a version level cap to prevent new service
version send RPC API messages that older versions may not
understand. This feature is described in nova's documentation:

.. code-block:: ini
[upgrade_levels]
compute=X+1
conductor=X+1

will keep the RPC version locked across the specified services to the
RPC version used in X+1. As all instances of a particular service are
RPC version used in X. As all instances of a particular service are
upgraded to the newer version, the corresponding line can be removed
from ``nova.conf``.
