Parse.Schema required fields and defaultValues

Closes: #930

Requires Parse Server 3.7.0+

Feature: parse-community/parse-server#5835

I added a FieldOption to addField and its counter parts. This will allow for future options like uppercase / lowercase for example.

I keep getting a schema mismatch when I use dates and pointers. @davimacedo Maybe you know why?
