discover: implement a periodic requery for network devices
If we boot a machine before external (network) dependencies are properly
configured, it will have tried once to download configuration, and
possibly failed due to that configuration not being present.
This change introduces a periodic requery of network resources. After a
timeout, petitboot will either re-acquire its DHCP lease (causing any
downloads to be re-processed, possibly with different parameters from
the new lease), or re-download a statically defined URL.
This timeout defaults to five minutes (similar to pxelinux), and is
configurable by DHCP option 211, "reboot time".
