[feature] Support funnelMaxStep function

[xiangfu0]

Support funnelMaxStep function to calculate max funnel steps for a giving sliding window. The syntax is:

FunnelMaxStep(timestampExpression, windowSize, ARRAY[stepExpression, ..], [mode, [mode, ... ]])

• timestampExpression is TIMESTAMP or LONG type;
• windowSize is LONG which indicate the sliding window size based on the value from timestampExpression;
• ARRAY[stepExpression, ..] is the steps to match;
• mode: Support multiple modes for funnel match - strict_deduplication, strict_order, strict_increase.

Sample query:

SELECT 
    userId, 
    FunnelMaxStep(
        timestampCol, 
        '1000', 
        ARRAY[ 
            url = '/product/search',
            url = '/cart/add',
            url = '/checkout/start',
            url = '/checkout/confirmation
        ],
        'strict_order' ) AS maxSteps  
FROM myTable 
GROUP BY userId 
ORDER BY userId

Sample response:

{
    "resultTable": {
        "dataSchema": {
            "columnNames": [
                "userId",
                "maxSteps"
            ],
            "columnDataTypes": [
                "STRING",
                "LONG"
            ]
        },
        "rows": [
            [
                "user0",
                4
            ],
            [
                "user1",
                3
            ],
            [
                "user2",
                3
            ],
            [
                "user3",
                1
            ]
        ]
    }
}
