    Don't inject settings for dynamic network

    When using Quantum for networking and setting flat_injected to
    inject network settings into the guest VM, Nova injects a static
    network configuration for networks using DHCP. This change
    checks for the existence of a dhcp server and, if found, does not
    inject static settings for that network.

    Due to limitations of the legacy network info, the fix only
    applies when new-style network info is passed to the injection
    template function. The only code still passing in legacy
    network info is in libvirt, and there is work ongoing to
    remove that dependency.

    Fixes bug 1163985
    Fixes bug 1112659
