Improvement Suggestion

The subcommand miner-multisig of lotus-shed lacks the change-worker function. The change-worker function requires the permission of onwer. If the onwer address is a multi-signature address, it is difficult to handle. Two subcommands can be added to enhance the modification of the multi-signature miner worker. address.
