Extend DAO Staking program for 3 months

The DAO Staking rewards program comes to its end on Jan 24th.

The current suggestion is to extend it for 3 months which gives the DAO enough time to move forward with the proposal on the token relaunch that's being actively discussed.

With 12,200 BOND distributed weekly, the APR was around ~50%. Considering that the DAO staking is the way to incentivize users to vote and subsidize the voting costs (not the actual yield farm), it might make sense to lower BOND emissions.

Here are the suggested options:

1. 12,000 BOND / week (~50%) = 144,000 BOND total
2. 8,000 BOND / week (~33%) = 96,000 BOND total
3. 6,000 BOND / week (~25%) = 72,000 BOND total
