ADD USB Code Update enable/disable

phosphor_usb_code_update is an application that use USB to do FW
update. phosphor_usb_code_update service is not a daemon, but an app
that will be called after inserting a USB flash disk.

This commit creates an object of phosphor_usb_code_update when
phosphor_usb_code_update is not started. We can enable/disable
phosphor_usb_code_update by setting the "Enabled" property to
true/false.

Please configure the “usb-code-update” option in your bb/bbappend to
enable this feature.

For phosphor_usb_code_update, useful rules files is
/lib/udev/rules.d/70-bmc-usb.rules. When usb code update is disabled,
srvcfg_manager creates an empty symlink
/etc/udev/rules.d/70-bmc-usb.rules, which causes
/lib/udev/rules.d/70-bmc-usb.rules inoperative. When usb code update is
enabled, srvcfg_manager deletes /etc/udev/rules.d/70-bmc-usb.rules.
