med: Add configure inventory commands
Default inventory information is fetched from dmi table. Most of embedded devices do not run EFI bootloader hence dmi information will not be available in /sys/class/dmi - Add `configure inventory` commands - Add `unconfigure inventory` commands - New code is dependent on enable-lldpmed - Add write support on lldpctl atoms - Add support for setting inventory configuration in daemon - Refactor `lldp_med` to assign `c_med_sw` only once. We have the configurability of inventory information, So it is not required for daemon to keep assigning `c_med_sw`
