Christian Heimes b57c818fab Use only TLS 1.2 by default
TLS 1.3 is causing some trouble with client cert authentication.
Conditional client cert authentication requires post-handshake
authentication extension on TLS 1.3. The new feature is not fully
implemented yet.

TLS 1.0 and 1.1 are no longer state of the art and now disabled by
default.

TLS 1.2 works everywhere and supports PFS.
