type ValidatorSetChangePacketData 

type ValidatorSetChangePacketData struct {
	ValidatorUpdates []types.ValidatorUpdate `protobuf:"bytes,1,rep,name=validator_updates,json=validatorUpdates,proto3" json:"validator_updates" yaml:"validator_updates"`
	ValsetUpdateId   uint64                  `protobuf:"varint,2,opt,name=valset_update_id,json=valsetUpdateId,proto3" json:"valset_update_id,omitempty"`

	// successfully slashed on the provider chain
	SlashAcks []string `protobuf:"bytes,3,rep,name=slash_acks,json=slashAcks,proto3" json:"slash_acks,omitempty"`
}

This packet is sent from provider chain to consumer chain if the validator set for consumer chain changes (due to new bonding/unbonding messages or slashing events) A VSCMatured packet from consumer chain will be sent asynchronously once unbonding period is over, and this will function as `UnbondingOver` message for this packet.
