TLS 1.3 Early Data can be used with PSK and not session tickets.
If only TLS 1.3 and no session tickets then no resumption.
External sites don't support TLS 1.3 yet.
1. Modify the other OCSP Stapling scripts to better manage the OCSP responder.
2. Modify the client's W option to take:
- 1 for Stapling v1
- 2 for Stapling v2
