Adding reboot throttling

For crashes during boot, Rescue Party will start rebooting and offering
factory resets as soon it detects those crashes. If the user
continuously rejects the factory reset prompts then the device will keep
rebooting and will never finish boot. There are some cases when the
device could have been saved if it would have finished the boot
(by server-side mainline rollbacks, GMS auto-updates, flag changes).

Adding throttling mechanism for reboots and factory resets. Rescue Party
won't be allowed to do new reboots and factory resets 10 minutes after a
factory reset was offered.
