[fast reboot] set a fast-reboot DB flag (sonic-net#887)

- This flag is currently no functional impact with just this change. - This flag is intended to coordinate fast-reboot shutdown path. - This flag enables moving fast-reboot per service knowledge to service scripts. which unblocks moving warm-reboot per service knowledge to service scripts. - This flag is consistent with the bootup flag we setting on the boot up path.
