* Update docs for timeslot.
* rename with_on_offence_fractions
* Add should_properly_count_offences
* Replace ValidatorIdByIndex with CurrentElectedSet
ValidatorIdByIndex was querying the current_elected set in each call, doing loading (even though its from cache), deserializing and cloning of element.
Instead of this it is more efficient to use `CurrentElectedSet`. As a small bonus, the invariant became a little bit easier: now we just rely on the fact that `keys` and `current_elected` set are of the same length rather than relying on the fact that `validator_id_by_index` would work similar to `<[T]>::get`.
