[PPL-Lang]Json function support for json_delete & json_extend

[YANG-DB]

Is your feature request related to a problem?
Continue Supporting the PPL Json grammar with adding the next functions:

• json_delete(object,[keys list])

  • Removes one or more keys and their corresponding values from the specified JSON object.
    • objects: the Json object is the field being evaluated
    • [keys list]: keys is the list of keys to remove from the object

• json_extend(object, [(path key, array values) list])

  • Adds multiple values to an array, json_extend flattens arrays into their component values and appends those values to the ends of the arrays.
    • objects: the Json object is the field being evaluated
    • [(path key, array values) list]): path key is the json path name of the array and the array values are the values to be added

Each designates an array or value within the object json document. The json_extend function adds the values of the corresponding after the last value of the array designated by the .

What solution would you like?

support the following json_delete

source = accounts | eval contacts = json_delete(contacts, ["addresses.email"])

support the following json_extend

` source = accounts | eval contacts = json_extend(contacts, "addresses.email", json_array("[email protected]", "[email protected]"))
