Dynamic Quorum Updates

TL;DR - increase max quorum from 15% to 20%

Dynamic Quorum Parameter Updates As articulated in this detailed post, three parameters need to be set for dynamic quorum.

CURRENT SETTINGS

1. Minimum quorum %: currently set to 10%
2. Maximum quorum %: currently set to 15%
3. Coefficient: currently set to 1, such that each against vote raises the quorum requirement by one vote, until the maximum quorum is reached.

PROPOSED SETTINGS

1. Minimum quorum %: 10% (no change)
2. Maximum quorum %: set to 20%
3. Coefficient: 1 (no change)

RATIONALE

1. Dynamic quorum was designed so that contentious proposals would require a higher degree of support.
2. Maximum quorum is currently too low to have changed the outcome of any recent proposals.
3. Increasing maximum quorum should increase the percentage of successful proposals that are "hell yes" initiatives.

_setDynamicQuorumParams: sets dynamic quorum params to:

1. Minimum quorum BPs: 10% (1000 basis points) (no change).
2. Maximum quorum BPs: 20% (2000 basis points).
3. Coefficient: 1 (1,000,000 in unsigned integer with 6 decimal places) (no change).
