CloudCode beforeSave and others need to be updated

[jaysonng]

Link to section:
https://parseplatform.org/Parse-SDK-JS/api/master/Parse.Cloud.html#.beforeSave

What is the issue?
From what I understand and found out from StackOverflow and the migration guide below, "response" has been deprecated

Can you propose a solution?
Based on this migration guide, maybe someone with better knowledge than I can fix up the deprecated api's to make use of the updated ones.
