Changing the minimum commission via staking configs requires use of the root track.  I've submitted [referendum 533](https://kusama.subsquare.io/referenda/533) in its place.

Update the various staking configurations .

* `min_nominator_bond`: The minimum active bond needed to be a nominator.
* `min_validator_bond`: The minimum active bond needed to be a validator.
* `max_nominator_count`: The max number of users who can be a nominator at once. When
  set to `None`, no limit is enforced.
* `max_validator_count`: The max number of users who can be a validator at once. When
  set to `None`, no limit is enforced.
* `chill_threshold`: The ratio of `max_nominator_count` or `max_validator_count` which
  should be filled in order for the `chill_other` transaction to work.
* `min_commission`: The minimum amount of commission that each validators must maintain.
  This is checked only upon calling `validate`. Existing validators are not affected.

RuntimeOrigin must be Root to call this function.

NOTE: Existing nominators and validators will not be affected by this update.
to kick people under the new limits, `chill_other` should be called.
