    CLOUDSTACK-265: provide option to turn-off automatic public IP association
    for each VM when using EIP service.

      - introduces Capability in the network offering, which decides when EIP
        service is used, by defualt public IP should be assigned to the VM or not

      - default network offering with EIP/ELB service will still work with old
        EIP semantics, i.e) assign a public IP to each VM on start
