Review Comment:
Since we need to add extra child field spec, so I refactor the logic and add
method `addFieldSpec(properties, column, fieldSpec);`
However this changes the order of column stats in the `metadata.properties`
files got changed.
Do you see this an issue for crc change?
E.g.
before:
```
column.column1.cardinality = 51594
column.column1.totalDocs = 100000
column.column1.dataType = INT
column.column1.bitsPerElement = 16
column.column1.lengthOfEachEntry = 0
column.column1.columnType = DIMENSION
column.column1.isSorted = false
column.column1.hasDictionary = true
column.column1.isSingleValues = true
column.column1.maxNumberOfMultiValues = 0
column.column1.totalNumberOfEntries = 100000
column.column1.isAutoGenerated = false
column.column1.minValue = 15935
column.column1.maxValue = 2147475579
column.column1.defaultNullValue = -2147483648
```
after:
```
column.column1.cardinality = 51594
column.column1.totalDocs = 100000
column.column1.bitsPerElement = 16
column.column1.lengthOfEachEntry = 0
column.column1.isSorted = false
column.column1.hasDictionary = true
column.column1.maxNumberOfMultiValues = 0
column.column1.totalNumberOfEntries = 100000
column.column1.isAutoGenerated = false
column.column1.columnType = DIMENSION
column.column1.dataType = INT
column.column1.isSingleValues = true
column.column1.minValue = 15935
column.column1.maxValue = 2147475579
column.column1.defaultNullValue = -2147483648
```
