Feature: Introduce Smart Scheduler (#99)

Change default scheduler to SmartScheduler Actions are prioritized in the following groups: 1- if any existing orders are behonds desired orderbook limits they are canceled in top priority 2- adjust levels liquidity, levels with biggest difference of liquidity between desired and current orderbook goes first 3- finally we cancel orders that are behonds the price points (far in the orderbook)

If we are short in liquidity (more than 120% of limit specified in orderbook), the priority of canceling group 3 becomes higher than group 2 actions until enough liquidity is available or no more orders are in group 3.
