Security policy (HSTS).
\since 5.9
\ingroup network
\inmodule QtNetwork
HSTS policy defines a period of time during which QNetworkAccessManager
should only access a host in a secure fashion. HSTS policy is defined by
RFC6797.
You can set expiry time and host name for this policy, and control whether it
applies to subdomains, either in the constructor or by calling \l setExpiry(),
\l setHost() and \l setIncludesSubDomains().
