deploy: add support for multiple bridges

deploy.py:
Some Fuel VMs may need more than one network interface. To be able to
provide that, we now allow the user to specify the "-b" paramter
(bridge) multiple times, creating a new NIC for each one of them.

The NICs are created in the same order as they are given in the command
line.

There is no change in behavior from earlier versions, pxebr will still
be the default bridge if none is specified in the command line.

deploy.sh:
To reflect the new capabilities of deploy.py, we introduce the
possibility to specify -B more than once in deploy.sh, and honor that
when calling deploy.py. We also make it possible to specify a comma
separated list of bridges, as in: -B br1,br2.
