Add current program cycle/counter status to the api

[Myles Metzler]

This will be added to the endpoint "/api/v1.1/chambers/1/operations" Note that /api/v1.0 remains the same for compatibility. /api/edge/ was added to allow access to the newest api version at all times.

On /api/v1.1/... or /api/edge/... routes that have the operations parameter now have operations.program.counters parameter:

  ...
  "operations": {
    "datetime": {
      "strftime": "Wed Apr 05 2017 08:36:54", 
      "uts": 1491381414.0
    }, 
    "mode": "Program Running", 
    "program": {
      "counters": [
        {
          "cycles": 99, 
          "end": 3, 
          "name": "A", 
          "remaining": 99, 
          "start": 2
        }, 
        {
          "cycles": 0, 
          "end": 0, 
          "name": "B", 
          "remaining": 0, 
          "start": 0
        }
      ], 
      "editor": "/program/editor?number=1", 
      "name": "CUBIC01", 
      "number": 1, 
      "step": 1, 
      "time_end": "Sun Apr 09 2017 12:56", 
      "time_step": "0:10:00", 
      "time_total": "100:20:00", 
      "uri": "http://webdevscp220/api/v1.1/chambers/1/programs/1"
    }
  },
  ...

On /api/v1.1/... or /api/edge/... routes that have the controllers parameter now have the stoppable parameter:

...
"controllers": [
    {
      "cascade": false, 
      "humidity": true, 
      "indConstant": true, 
      "model": "Espec,SCP220", 
      "stoppable": true
    }
  ],
  ...
