Given the concerns about the dispatcher being stuck in a suppressed state,
I'm going to solve this a different way. I'm going to increase the default
offer decline timeout to 120s and make it configurable, just like it is in the
driver. This will make it so that the offer will be offered to 120 other
frameworks before circling back to the dispatcher, rather than the default 5.
I'll also keep the explicit revive calls when a new driver is submitted or an
existing one fails, which immediately causes offers to be re-offered to the
dispatcher.
This removes the risk that the driver gets stuck in a suppressed state,
because the dispatcher never suppresses itself.
