Produces a curl command like this, which is super handy!

curl https://alertmanager1.internal.net:9093//api/v1/silences
  -X POST --data {
  "matchers": [
    {
      "name": "alertname",
      "value": "SshProbeFailing",
      "isRegex": false
    }
  ],
  "startsAt": "2018-08-23T21:34:50.845Z",
  "endsAt": "2018-08-23T22:34:50.989Z",
  "createdBy": "test_user@test.com",
  "comment": "I'm fixing this..."
}

But, it doesn't include the TLS settings (e.g. from the config file or commandline args). If TLS options are included, it should look more like this...

curl https://alertmanager1.internal.net:9093//api/v1/silences --cert /var/certs/cert.pem --key /var/certs/pkey.pem
  -X POST --data {
  "matchers": [
    {
      "name": "alertname",
      "value": "SshProbeFailing",
      "isRegex": false
    }
  ],
  "startsAt": "2018-08-23T21:34:50.845Z",
  "endsAt": "2018-08-23T22:34:50.989Z",
  "createdBy": "test_user@test.com",
  "comment": "I'm fixing this..."
}
