Fuse staking for G$ rewards

[sirpy]

Upgrade current FuseStaking contract

• stakers should get gFuse tokens
• staker should be able to choose giveBackRatio to DAO (out of his rewards, min 10% - parameter)
  • notice you need to keep an average of donated ratio globally and per staker
  • notice when transferring tokens, the donation ratio for received tokens will be the same as the current receiver average
• suggest and implement solution fuse staking is locked for 7 days
  • withdraw buffer or triple withdraw (submit intent, withdraw all daily intents, after 7 days withdraw your stake)
  • other?
• collect rewards and calculate DAO part(ie give back ratio) vs stakers part
  • DAO part, according to cap/minimum, should go to: fusefaucet (fuse), firstclaim (gd), invite pool(gd), UBI (gd), community pool (gd)
  • stakers part (gd)
• DAO part target distribution - how much should be sent to fusefaucet/firstclaimpool/invitepool
  • fusefaucet, firstclaim, invitepool - calculate spending rate (current balance vs previous recorded balance). should have reservePeriodDays(default 1 week) of spending at current rate. if below target balance then send enough to cover last epoch spent amount + reserveTopExtra (default 10%).
    notice fusefaucet is in FUSE tokens while firstclaim/invite are GD
  • UBI/Community pool - split according to set percentages
• define guardian role - on top of Avatar - able to pause, set reservePeriodDays, ubi/community percentages, min giveBackRatio
