deploy: Networking fixes

Introduce /etc/network/interfaces.synnefo that will setup bridges
used for VMs' public and private networks.

Instead of using a common bridge use two separate bridges (br0,
prv0). Their default ports are defined in nodes.conf
(vm_public_iface, vm_private_iface) which are by default dummy. In a
single node setup we don't need those interfaces. In case of router
node, br0 will get the gateway IP.

Use ferm for persistent network configuration. Add masq.ferm that
is responsible for masquerading on router node and MAC SNAT on all
nodes (needed in case we have a MAC filtered setup on
vm_public_iface).

Use rc.local to losetup extra disk and ifup bridges.

deploy: Fix GanetiDev component

This component is supposed to clone a ganeti repo and setup
a Ganeti QA cluster.

We provide a qa-init.sh that installs all required packages (apt-get
install and cabal install) and prepares the node for QA.

We provide a configure-ganeti similar to the one the debian packages
use so make install && /etc/init.d/ganeti restart will override
the existing binaries.

To install ganeti from source run on all nodes:

 # cd /srv/srv/ganeti
 # ./qa-init.sh
 # ./configure-ganeti
 # make && make install
 # cp doc/examples/ganeti.initd /etc/init.d/ganeti
 # /etc/init.d/ganeti restart

To run the QA do:

 # cd /srv/src/ganeti/qa
 # PYTHONPATH=/srv/src/ganeti/ ./ganeti-qa.py --yes-do-it /root/qa-sample.json

deploy: Fix setup of admin user

The group-add and user-modify snf-manage commands are available only
in Astakos node. Therefore we cannot run them on Admin node if
snf-admin-app runs on a different node that snf-astakos-app.

deploy: Fix Admin component

In case we test the deployment with local packages we have
to install snf-cyclades-app, snf-astakos-app, and
python-astakosclient manually.

This way, if Kamaki setup fails for some reason (after adding the
