[PATCH] cert based client authentication

TLS/SSL Options does not apply to the dynamically generated certificates

The TLS/SSL options configured with http_port configuration parameter
does not used to generate SSL_CTX context objects used to establish SSL
connections. This is means that certificate based authentication, or SSL
version selection and other SSL/TLS http_port options does not work for
ssl-bumped connection.

This patch fixes this problem.
