Convert enable-internal-tls.yaml to be generated

All of the other SSL environments were converted, but this one was
missed.  That's an inconsistent user experience and should be
cleaned up.

This environment also exposed a bug in the tool where it did not
include the parameter_defaults section key if all the parameters
were marked static.
