    Uniquify horizon messages returned in a single response

    A network operation can fail because of different
    reasons - yet in many places just one error message
    is provided. Combined with too broad exception clause,
    and incorrect assumptions on the reasons of failure
    (e.g. Neutron service being unavailable causes all
    other sorts of errors like inability to Allocate IP
    or Associate it) this leads to multiple errors when just one
    would suffice. The fix aims to provide sensible error
    messages in case the network service is down. This includes
    returning only unique messages in a single response.
