mqttwebview's Issues

Send fbp discovery messages periodically

Right now we're using a foreign participant declaration to make our "showurl" participants (provided by this software) to show up in c-flo:

https://github.com/c-base/c-flo/blob/master/participants/showurl.yml

It would be preferable for each mqttwebview instance to send these discovery messages itself. This way we could remove these foreign participants from c-flo, and each new mqttwebview instance would appear automatically in the c-flo graph when it becomes online.

mqttwebview should send these messages to the fbp topic at start up, and periodically after that (every 60 seconds is a good default).

Here are examples of how these discovery messages look like:

{
  "command": "participant",
  "protocol": "discovery",
  "payload": {
    "component": "c-base/farbgeber",
    "inports": [
      {
        "queue": "farbgeber.IN",
        "type": "bang",
        "id": "in"
      }
    ],
    "label": "Produce pleasing color palettes",
    "outports": [
      {
        "queue": "farbgeber.PALETTE",
        "type": "object",
        "id": "palette"
      }
    ],
    "role": "farbgeber",
    "id": "farbgeber92490",
    "icon": "tint"
  }
}

{
  "command": "participant",
  "protocol": "discovery",
  "payload": {
    "component": "c-base/boardingurl",
    "inports": [
      {
        "queue": "boardingurl.IN",
        "type": "object",
        "id": "in"
      }
    ],
    "label": "Generate greeting URL for crew members that are boarding",
    "outports": [
      {
        "queue": "boardingurl.OUT",
        "type": "string",
        "id": "out"
      }
    ],
    "role": "boardingurl",
    "id": "boardingurl3406",
    "icon": "check"
  }
}
