[noPoll] Server PSK Callback via nopoll_ctx_set_ssl_context_creator

[Chris Buchter]

Just ran through a debugger, and it hits the lines that you were referring
to. Some of my configuration for the SSL_CTX is being applied. For example,
the handshake fails for any connection that is not using one of the ciphers
I have configured in initialize_ssl(). But the callbacks are still not
being used
