ML2: validate network configuration

[Manish Godara]

Validate that each physical_network name is neither empty nor too long. When a network is added we should make sure the physical_network name is appropriately configured (see comments in code plugins/ml2/drivers/type_flat.py as well type_vlan.py)

    validate flat networks physical name

    Modified flat driver to validate the physical network
    name - we make sure that empty names are deducted.

    unit test changes:
    - added two tests to make sure that we detect empty
      physnet names
    - fix bug in existing unit-tests
    -- flat_networks should be a list of string and not string
    - use conf to setup flat_network
