Refactor bridge and mac-prefix pool tables

Redesign the implementation of pools and map mac-prefix and bridge pools
to that design.

Each pool type is mapped to a table in the database, and each row of
that table is a pool of that type. All pool tables must contain the...

New method for creating BackendNetwork entries

Create a new method to the Network model, in order to create the
BackendNetwork entries tha correspond to this network. Also remove
the custom save method, since when multiple public network will be
supported, we want them to be correlated with specific backends.

Implement multiple public networks

Implement multiple public networks in order to support:
- different public networks per backend
- non-consecutive IP ranges in each backend

To support this, public networks are treated different from private
ones. Namely, they are correlated with one backend (and so have...

Do not allow creation of two big/small networks

- Networks smaller than /29 are not supported in Ganeti.
- Big networks will result in degraded performance in Ganeti
and DB due to the big reservation map.

Catch error caused by duplicate NIC removal in ui

NICs get removed once their associated vm or network trigger their
corresponding remove signal. Synchronous removal of vm/network will
cause duplicate NIC removes to be called.

Fix migration files

Fix south migration files. In data migrations, access the Models from
the orm, instead importing Models from synnefo.db. This is necessary as
