Migrate shared API Subject specs from Gumboot
Migrate shared API Subject specs from Gumboot

We intend to override how ApiSubject is implemented in order to store a
token for API authentication along with x509_cn as currently
implemented.

To support this we need to modify all associated specs locally as this
change does not apply to other Gumboot apps.
