Packaging updates and notes for downstreams

• Switched to using the :mod:propcache <propcache.api> package for property caching
  -- by :user:bdraco.

  projects.

Bug fixes

  instead -- by :user:mjpieters.

Features

• Added :attr:~yarl.URL.host_subcomponent which returns the :rfc:3986#section-3.2.2 host subcomponent -- by :user:bdraco.

  The only current practical difference between :attr:~yarl.URL.raw_host and :attr:~yarl.URL.host_subcomponent is that IPv6 addresses are returned bracketed.
