Pass selected field to Cloud Function script

Current Limitation

Currently, it cannot be determined which field was been selected when a script has been invoked.

Feature / Enhancement Description

Pass the selected field as a separate parameter to the Cloud Function payload.

For example the dashboard user should be able to invoke a script on a user in a specific field of the selected object:

• Transaction class: buying user, selling user

Knowing only the "transaction" object is not enough to know on which user the Cloud Function should be executed.

Example Use Case

Parse.Cloud.define('deleteUser', async (req) => {
  const selectedTransaction = req.params.object;
  selectedTransaction.set('invalid', true);
  await selectedTransaction.set.save(null, { useMasterKey: true });

  const selectedUser = req.params.selectedField;
  if (selectedUser instanceof Parse.User) {
    selectedUser.set('deleted', true);
    await selectedUser.save(null, { useMasterKey: true });
  }
});

Alternatives / Workarounds

None.

@dblythy What do you think?

Sounds good

[mtrezza]

To avoid any confusion for future readers, in your PR you're passing the name of the selected field, instead of the value of the selected field as suggested in the example use case. I think that makes more sense, because if there are 2 fields of the same type with the same value it wouldn't be possible to know which field was selected.
