    Set SUBNETPOOL_PREFIX_V4 to FIXED_RANGE

    The default for SUBNETPOOL_PREFIX_V4 in devstack causes external
    connectivity to be mostly broken in osic-cloud1 nodes. IPA relies on
    external activity to build images, and osic-cloud1 is pretty prevalent
    for running CI jobs, therefore this breaks IPA CI.

    Setting this to the same range as FIXED_RANGE should eliminate this, or
    at least reduce the probability of it happening from 1:(size of /8) to
    1:(size of /24).

    This should be reverted when the actual problem is fixed in devstack.
