Make resolver HTTP timeout setting implementation neutral
Rather than exposing the underlying mechanism (LWP) for the HTTP
request via the "lwp_timeout" setting, use "request_timeout" so that if
we switch to a different HTTP library the setting name doesn't
contradict it.
Also, add an example setting to opensrf.xml.example.
