      Before committing a migration this check is ensuring that the bounds are valid shard keys.

      Given that moveRange is choosing a bound relying on the output of autoSplitVector, we should make sure that it never returns invalid split points. This will help to:

      • Avoid wasting time cloning before failing the commit
      • Avoid repeatedly selecting invalid split points

      This ticket is an optimization that will not be needed in case SERVER-12536 gets done.
