Update certificates to include localhost and 127.0.0.1

This updates the certificates to have subjectAltName defined as

subjectAltName=DNS:$1,DNS:localhost,IP:127.0.0.1

It allows clients from the localhost to connect.
We're debating if we need the IP:127.0.0.1 going forward,
so this might change in the future.
