dnsresponse_: enable verifying responses

Browse source

add option verify to enable graphing the number of successful responses.

succeeded.

add option timeout to be able to limit the time the plugin takes for
unresponsive servers. old max time was 75 seconds times 20 (25minutes).

added warnings if average and or mean get close to the timeout.
