[BUG] In QUALX, the value of sql_ops_xxx is binary.

[fang-tech]

Describe the bug
In qualx tool, featurizer default.py, sql_ops_xxx feature's value is 0/1.
However, based on the comments and variable names, the values of these features should all be the number of occurrences of this node.

Steps/Code to reproduce bug

    # count occurrences
    sql_ops_counter['counter'] = 1  # counter col for pivot_table()
    sql_ops_list = list(sql_ops_counter['nodeName'].unique())  # unique sql ops
    sql_ops_map = {cc: 'sqlOp_' + cc for cc in sql_ops_list}  # add prefix to sql ops
    sql_ops_counter['nodeName'] = sql_ops_counter['nodeName'].map(sql_ops_map)
    sql_ops_list = list(
        sql_ops_counter['nodeName'].unique()
    )  # update unique sql ops list

    # pivot sql ops rows to columns
    sql_ops_counter = (
        pd.pivot_table(
            sql_ops_counter,
            index=['appId', 'sqlID'],
            values='counter',
            columns='nodeName',
        )
        .fillna(0)
        .astype(int)
        .reset_index()
    )

Expected behavior
The sql_ops should be aggregated through the sum function. Be like:

        pd.pivot_table(
            sql_ops_counter,
            index=['appId', 'sqlID'],
            values='counter',
            columns='nodeName',
            aggfunc='sum'  # Sum to count total occurrences
        )
