Bug fix: 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.
