    [Functional] Increase test_timeout for db migration tests

    In Neutron we hit quite often same issue as Manila, see [1] for
    details.
    It looks that solution for this problem may be increase timeout
    for test_walk_version functional tests.
    Higher timeout will be applied for tests for both pgsql and mysql
    backends but it is mostly needed for mysql because 'pymysql' works
    much slower on slow nodes than 'psycopg2'

    This patch adds also new decorator to set individual timeout for
    tests.
