Indices of validators that have offended in the active era. The offenders are disabled for a
whole era. For this reason they are kept here - only staking pallet knows about eras. The
implementor of [DisablingStrategy] defines if a validator should be disabled which
implicitly means that the implementor also controls the max number of disabled validators.
The vec is always kept sorted so that we can find whether a given validator has previously
offended using binary search.
