Force unlock message

[ValarDragon]

Background

For Mars, we need to add a "ForceUnlock" message for LP's where they can break locks they own immediately. However permission for their address to use this needs to be given by governance, based upon contract audits.

Suggested Design

Design of force unlock:

• There is a chain parameter for the addresses that are allowed to have force unlock for their own locks
  • (Governance can update this list through either param change proposal, or custom proposal type. I'd prefer param change)
• We add a message called "ForceUnlock" which takes in a lock ID and amount, and asserts that:
  • lock owner = msg sender
  • lock is not superfluided
  • {partial unlocks that amount immediately}

Acceptance Criteria

• Force unlock message exists
• Above constraints are met
