commit ac676033b595286702fd2c56183b87c85ce7574a
Author: atanasova <atanasova@chromium.org>

Add report URL to safe search API functionality.

Add apiary request creator that gets the appropriate auth token and
sends a request ot the SafeSearch API.
Currently this is attached to supervised user services and a child
will be able to issue such request.
I have added feature flags that disable the apiary creator from
being added to the supervised user services and this disables the
whole feature.
