Consul config error with TLS and Connect

[Demivan]

Enabling both TLS and Connect generates config that Consul refuses to accept.

consul[10798]: ==> the `ports.grpc` listener no longer supports TLS. Use `ports.grpc_tls` instead. This message is appearing because GRPC is configured to use TLS, but `ports.grpc_tls` is not defined
systemd[1]: consul.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: consul.service: Failed with result 'exit-code'.
systemd[1]: consul.service: Service hold-off time over, scheduling restart.
