OCSP stapling: ssl_stapling_verify directive.
OCSP response verification is now switched off by default to simplify
configuration, and the ssl_stapling_verify allows to switch it on.
Note that for stapling OCSP response verification isn't something required
as it will be done by a client anyway. But doing verification on a server
allows to mitigate some attack vectors, most notably stop an attacker from
presenting some specially crafted data to all site clients.
