[Feature Request] API for available instances

[vzool]

Hi, I'm looking forward to an API that lists all public instances in the chronicle app, then this will lead us to hide other instances for some use cases. By that in mind I suggest to update local/settings.json to support this feature like the following:

{
  ...

  "instances": {
    "": {
      "name": "",
      "public": true,
      "desc": "Default public instance"
    }
  },

  ...
}

I mean by public if set to false is just to hide the instance in the suggested API result. Thanks

Making some replication instances publicly discoverable from an API makes sense to me. (The ability to run secret replicas is helpful for some threat models, but having some public instances don't hurt anything.)

Indeed, this will stage an important role for "Chronicle Explorers". ^_^

This will be done in the next release.
