harder to write latex with the docstring syntax.

Part of #33871, closes #33831.

since rounding already returns 1 as minimum.

instead of bw before scaling.

Tests have finally correct value.
For 1 result, only when the cap is 1, the value will be equal to the
rounded bw because the cap does not limit it.

Make tests pass because the high limit change the expected values,
but the final value still needs to be fixed.

Make test pass, though the value is not correct since it needs to be
rounded after clipping

Take either the consenus bandwidth or the descriptor bandwidth if
one of them is missing, do not scale when both are missing and
ignore descriptor average and burst when they are missing.

Scale relays without average or observed bandwidth.
Later it will be check what to do if their values are None or 0

since they are probably due a bug.

for each relay, calculate the filtered mean for all relays and
calculate the filtered ratio for each relay.

When using `_relays_with_flags()` and similar methods it's possible
that tests start to hang without time freezing. See bug 33748 for more
details. We work around this by providing the necessary `freeze_time()`
calls meanwhile.
