Server doesn't fail if I specify the -L parameter and don't provide a certificate and key.

If I start the server like this:

nimblex:~# ./nettest-linux-x86_64/nettest -s -L 10.50.2.3:334
Reading config from: "/etc/nettest.conf"
TCP Server will listen on 0.0.0.0:5105

Instead of failing because a certificate or key was not specified either in the CLI or config file, it just ignores the -L parameter. Common behavior among Linux software is to fail, but at the very least, it should provide a warning.
