    Test that value is within a reasonable range of password.

    The following ratio calculations are based on testing SequenceMatcher like
    this:

    for i in range(0,6):
      print(10**i, SequenceMatcher(a='A', b='A'*(10**i)).quick_ratio())

    which yields:

    1 1.0
    10 0.18181818181818182
    100 0.019801980198019802
    1000 0.001998001998001998
    10000 0.00019998000199980003
    100000 1.999980000199998e-05

    This means a length_ratio of 10 should never yield a similarity higher than
    0.2, for 100 this is down to 0.02 and for 1000 it is 0.002. This can be
    calculated via 2 / length_ratio. As a result we avoid the potentially
    expensive sequence matching.

    Validate that the password is sufficiently different from the user's
    attributes.

    If no specific attributes are provided, look at a sensible list of
    defaults. Attributes that don't exist are ignored. Comparison is made to
    not only the full attribute value, but also its components, so that, for
    example, a password is validated against either part of an email address,
    as well as the full address.

    The password is rejected if it occurs in a provided list of passwords,
    which may be gzipped. The list Django ships with contains 20000 common
    passwords (lowercased and deduplicated), created by Royce Williams:
