Add FunnelCompleteCount aggregation function

[xiangfu0]

• Add FunnelCompleteCountAggregationFunction to calculate how many completed count of funnels;
• Add FunnelMatchStepAggregationFunction to calculate the funnel match array;
• Extract common logic to FunnelBaseAggregationFunction for
  • FunnelMaxStepAggregationFunction
  • FunnelCompleteCountAggregationFunction
  • FunnelMatchStepAggregationFunction

Changed the function syntax a bit to:

FunnelMaxStepAggregationFunction(timestampExpression, windowSize, numberSteps, stepExpression, [stepExpression, ..], [mode, [mode, ... ]])

E.g.

SELECT 
            userId, funnelMatchStep(timestampCol, '1000', 4, 
            url = '/product/search', 
            url = '/cart/add', 
            url = '/checkout/start', 
            url = '/checkout/confirmation', 
            'strict_increase' )
FROM 
            myTable 
GROUP BY userId ORDER BY userId LIMIT 100
