New handler triggers copying of VIPs from given original cluster to new
one. The reason for separation of this action from copying of network
configuration is that accordion to [1] copying of existing VIPs/allocation
of new ones will not take effect for new cluster unless it has assigned
nodes. Thus in context of cluster upgrade procedure VIP transfer must be
done after node reassignment, and as long as nodes are being operated on
one by one it would be not efficient to call VIP copying method after
each such reassignment.
Tests updated accordingly.

The change introduces Nailgun extensions which use stevedore to
plug into nailgun. Stevedore enables (not only) Fuel developers
to write extensions and develop them independently in separate
repos.
Functions for loading and retriving extensions classes was
moved to new file `manager.py`.

The patch adds method that assigns a node to an upgrade cluster without
deleting it from DB. This allows to keep ID of the node and IP addresses
assigned to it. The node is booted into the bootstrap image as soon as
it moves to an upgrade cluster.

The patch adds an extension which implements the procedure of upgrading
clusters from one major release to another. As a first step of the
procedure the extension provides an ability to create a seed cluster
with the same settings as the original.
