mod_pubsub_serverinfo: New module that uses pub/sub to make accessible server info This first implemetnation is laughably simple: it only adds a disco#info feature. This flags 'opt-in' for inclusion of local domain names in the data exposed by other domains (per the domain), which will allow servers to be listed in the XMPP Network Graph at https://xmppnetwork.goodbytes.im Hopefully, this bare-boned implementation acts as a stepping stone for future improvements.

Simple module adding an endpoint meant to be used for health checks.

# Configuration

After installing, enable by adding to [`modules_enabled`][doc:modules_enabled] like many other modules:

``` lua
-- in the global section
modules_enabled = {
    -- Other globally enabled modules here...
    "http_health"; -- add
}
```

## Access control

By default only access via localhost is allowed. This can be adjusted with `http_health_allow_ips`. The following example shows the default:

```
http_health_allow_ips = { "::1"; "127.0.0.1" }
```

Access can also be granted to one IP range via CIDR notation:

```
http_health_allow_cidr = "172.17.2.0/24"
```

The default for `http_health_allow_cidr` is empty.

# Details

Adds a `http://your.prosody.example:5280/health` endpoint that returns either HTTP status code 200 when all appears to be good or 500 when any module
[status][doc:developers:moduleapi#logging-and-status] has been set to `error`.
