For reviewer(s),

1. GetFutureSwapBlock RPC is independent of Oracle, Loan, User accounts, or RPC like futureswap. The value of GetFutureSwapBlock RPC is ONLY determined by Gov attributes, block count or futureInterval values.

2. Gov attributes: active = false can only be set BEFORE reward_pct and block_period values are set. Gov attributes: active = true can only be set AFTER reward_pct and block_period values are set.
