    Use SQL BigInteger type to store BGP LOCAL_PREF

    The new route control API extension allows to define BGP LOCAL_PREF for
    the routes that will be advertised. BGP LOCAL_PREF maximum value is
    2^32-1 and the SQL Integer type is limited to 2^31-1.
    Cannot add a unit test as unit test framework uses an in-memory sqlite3
    DB and its Integer type maximum value is 2^64-1. Need to add a
    functional test.
