one-time-feat: shed: FIP0036 post poll result processing

[jennijuju]

What the heck is this?

ICYMI
We've got an FIP-0036
Then we've got an FilPoll for FIP-0036 - GO VOTE if you haven't already, before that DYOR!
Then we've got some governance rules - in which we got Who gets to vote?

This is a set of shed cmd to process the poll result according to the governance rule.

Disclaimer: code reviews are welcomed - its possible something was mess-up somewhere, we are going to keep it updated base on feedbacks!

So.. how?

We use the offline mode here to inspect the state that the poll snapshot was taken.

A couple source needed:

• a lotus chain datastore that has the state of height 2162760, state root bafy2bzacebdnzh43hw66bmvguk65wiwr5ssaejlq44fpdei2ysfh3eefpdlqs (according to filscan)
• your daemon node thats linked with the datastore needs to be stopped given we need to lock the datastore for accessing the state
• you will need to know who voted: https://api.filpoll.io/api/polls/16/view-votes
• the shed cmd are developed based on the facts/assumption that
  • fil-poll doesn't take duplicated entry from the same signer
  • we only use fil-poll to get signer address & their vote option
  • vote option can either be 49 - approve, or 50- reject
  • everything else, we get the data from the chain state, includes account balances, multisig info, deal info and miner actor info.
• the shed tool took two argument, first one being the state root, the second one being a json file contains the votes that have attributes signerAddress and optionId for each vote entry.
