The store is using QSettings under the hood. A user can enable/disable
storing HSTS policies (via QNAM's setter method) and we take care of
the rest - filling QHstsCache from the store, writing updated/observed
targets, removing expired policies.

HTTP Strict Transport Security (HSTS) is a web security policy that
allows a web server to declare that user agents should only interact
with it using secure HTTPS connections. HSTS is described by RFC6797.
This patch introduces a new API in Network Access Manager to enable
this policy or disable it (default - STS is disabled).
We also implement QHstsCache which caches known HTTS hosts, does
host name lookup and domain name matching; QHstsHeaderParser to
parse HSTS headers with HSTS policies.
A new autotest added to test the caching, host name matching
and headers parsing.
