Account provisioning customisations doesn't have api helper scripts

[awsome-user]

Describe the outcome you'd like

There is no way as of now to use private GitHub repositories in the account provisioning customizations phase as there is no shell invocation such as pre-api-helpers.sh for the global customizations.

Is your feature request related to a problem you are currently experiencing? If so, please describe.

The aft workshop describes use cases such as adding custom step functions and lambdas to be called by the aft-account-provisioning-framework step function. Many enterprises define their own modules for lambda functions and other resources which can not be used unfortunately.

Using private github terraform repos at this point would also allow for better testing. A pre-release branch could be used in a sandbox set-up and the main branch in a prod set-up. This allows following git flow to first test features in a separate environment.
