    MDL-66979 behat: Goutte driver doesn't implement setTimeouts()

    Also, change:

    get_real_timeout(30000)

    to:

    get_real_timeout(30) * 1000

    because the original functions are defined to use seconds, and
    having the 1000 around will help us detecting cases in the case
    of a hypothetical review of uses.
