// UpdateFirmwareRemote() uses 'gofish' to update the firmware of a BMC node.
// The function expects the firmware URL, firmware version, and component flags to be
// set from the CLI to perform a firmware update.
// Example:
// ./magellan update https://192.168.23.40 --username root --password 0penBmc
// --firmware-url http://192.168.23.19:1337/obmc-phosphor-image.static.mtd.tar
// --scheme TFTP
//
// being:
// q.URI https://192.168.23.40
// q.TransferProtocol TFTP
// q.FirmwarePath http://192.168.23.19:1337/obmc-phosphor-image.static.mtd.tar
