Title: Initial API release

No docs to go with this just yet but it's pretty simple. Two examples:

Get a port graph:
curl -H "X-Auth-Token: YOURTOKENHERE" http://URL/api/v1/get/graph/port/hostname/DEVICENAME/IFNAME

Get port statistics:
curl -H "X-Auth-Token: YOURTOKENHERE" http://URL/api/v1/get/stats/port/device/DEVICEID/IFNAME
