SLA Monitoring via REST API

This feature adds the ability to monitor the SLA log information and interface SLA information using the REST API. This feature is also be used by FortiManager as part of its detailed SLA monitoring and drill-down features.

Interface log command example:

https://172.172.172.9/api/v2/monitor/virtual-wan/interface-log
{
  "http_method":"GET",
  "results":[
    {
      "interface":"port13",
      "logs":[
        {
          "timestamp":1547087168,
          "tx_bandwidth":3447,
          "rx_bandwidth":3457,

          "rx_bytes":708799,
          "egress_queue":[
          ]
        },
        {
