Support Custom Compare Rule

Source Data

baseJson: [{
  "a": 100,
  "b": 100
}]

actualJson:
[{
  "a": 101,
  "b": 105
}]

Custom Rule

threshold = 0.01
diff = abs((actualJsonValue - baseJsonValue)/baseJsonValue)
if diff > threshold; then regard as diff;
else, it regard as no diff

In this case
abs((101-100) / 100) > 0.01 is false, so key a is  no diff
abs((105-100) / 100) > 0.01 is ture, so key b is diff
