Add option if it doesn't exist on CRM create/update APIs

[CDean]

When you add or update a record (contact/company/etc.), it gets denied if an option within a property doesn't exist.  I propose adding an option to the API to allow adding the option if it doesnt exist.

E.g.

Favorite Color (Checkbox)

Red, Blue, Green

Add/Update Contact

Name: Roger

Email: test@test.com

Favorite Color: Orange

---

Currently, this will error.  I want an option to make it so it adds the option to the property and succeeds.
