[Feature] AMM compatibility

[dmvt]

User Story

• As an <audience/user>: DAO
• I want to <action/task>: my tokens to be compatible with AMMs that support the sync() function
• so that <outcome/goal/benefit>: my token prices don't break

Type

• Enhancement
• Maintenance
• Refactor

Description

AMMs are not automatically aware of rebases in their favor.

Definition of Done

• an array of AMM addresses exists on ElasticDAO
• a function to add an AMM address exists (controller guard)
• a function to remove an AMM address exists (controller guard)
• ElasticDAO.join calls sync() on each AMM stored
• 100% test coverage
