Remove all data structures concerning a staker/stash once it is at a state where it can
be considered dust in the staking system. The requirements are:
the total_balance of the stash is below min_chilled_bond or is zero.
or, the ledger.total of the stash is below min_chilled_bond or is zero.
The former can happen in cases like a slash; the latter when a fully unbonded account
is still receiving staking rewards in RewardDestination::Staked.
It can be called by anyone, as long as stash meets the above requirements.
Refunds the transaction fees upon successful execution.
Parameters
stash: The stash account to be reaped.
num_slashing_spans: Deprecated. This parameter is retained for backward
compatibility. It no longer has any effect.
