Bug Description
The AWS documentation says that account_customizations_name is optional, and so it has been every time I've deployed AFT for a client, but now leaving it out yields an error message.

To Reproduce
Steps to reproduce the behavior:

1. Submit an account provisioning request not containing account_customizations_name

Expected behavior
I expect an account to be created or updated.
