Add a hack to make AWS Roles usable

Enable using a manually-generated session token for AWS Roles.

A better solution would be to use
https://docs.ansible.com/ansible/latest/modules/sts_assume_role_module.html,
but I'm not sure how to add the conditional logic required to add that
to the Streisand setup workflow.
