travelmate: update 0.7.0

* no longer misuse ubus/procd service object for travelmate runtime 
  information, now save all required information directly
  in a JSON file/format
* new 'status' init command to print runtime information
* add a configurable interface trigger timeout for
  nested & slow modem/router setups, set 'trm_triggerdelay' accordingly
* change start priority & refine reload timings
* cosmetics
