discover: Support DHCP "pathprefix" configuration option
This change implements support for the DHCP "pathprefix" option. We use the following logic: - If pathprefix is present and a full URL, we base the config file location on pathprefix + conffile - If pathprefix is present but not a full URL, we use it as the path component of the URL, and pick up the host from other parameters in the DHCP response - If no pathprefix is present, we determine the configuration prefix from the DHCP bootfile parameter.
