RHEL 7 HAProxy 1.5.x and custom openssl engines

Hi,

I was wondering if there is an option, like in apache mod_ssl 'SSLCryptoDevice engine' to change the default cryptoengine to use Hardware Security Modules (for example Thales/nCipher chill engine)? I know that HAProxy uses openssl as a encryption/SSL/TLS layer, so it might be very useful.
