FIP-0074: CLI to invoke the new SettleDealPayments method

[arajasek]

SPs will now need to invoke this method in order to settle deal payment. The lotus-miner should expose functionality to do so.

This method will be similar to, and should be placed alongside, the existing actorWithdrawCmd (here), which performs a similar operation.

@arajasek @jennijuju Can you please confirm if there is an existing idea about how to create the bitfield for the params? I am just trying to figure out which deals to include in params. I can filter out based on provider but how do I ensure that I am not including the deals which are not going to result in anything and just waste the gas. Or is my assumption about the waste of gas wrong here?

@LexLuthr are you still planning to work on this?

I would included two levels of granularity. First just filter by provider id. The gas costs shouldn't be significant in the common case. Second users can provide a list of deal ids if they really want fine grained control.

@ZenGround0 I won't be able to work on this at this time.

Hey @rjan90 Can I work on this?

Hey @akaladarshi,

Feel free to take this on. If you have any questions or need guidance, don't hesitate to ask here on GitHub or in the #fil-lotus-dev channel on Filecoin Slack.

Hey @rjan90, I have raised a draft PR for now. Please review it and let me know if this is the correct implementation.

I am little bit confused about payments for the deal, it was mentioned in FIP-0074 that the gas fee will be paid by the invoker of the function.
