[LIP #4.1] Community rewards - Quarterly pool size

As LIP #4 ( https://commonwealth.im/lattice-gateway/discussion/9888-lip-4-community-rewards-governance-voting-rewards ) layed out the governance system should reward users for their activity and participation. For this reason LIP #4 implemented an annual reward pool and a quarterly reward pool to incentivize long-term and short-term participation with a total of 1,000,000 $LTX per year.

Based on the long-term model of the veLTX system, this proposal suggests having the majority of rewards going into the annual pool to strongly encourage the long-term participation of veLTX holders in our governance system.

Depending on Lattice Gateway's future situation, the following number may be reviewed and changed in the DAO treasury policies.

The voting will decide the size of the quarterly pool with three different options and last for 7 days:

1. 15 % of the total rewards (150,000 $LTX)
2. 20 % of the total rewards (200,000 $LTX)
3. 25 % of the total rewards (250,000 $LTX)
