mod_http_xep227: Add support for import via APIs rather than direct store manipulation In particular this transitions PEP nodes and data to be imported via mod_pep's APIs, fixing issues with importing at runtime while PEP data may already be live in RAM. Next obvious candidate for this approach is rosters, so clients get immediate roster pushes and other special handling (such as emitting subscribes to reach the desired subscription state).

This module publishes data from [Prosody's `internal` statistics][doc:statistics]
 into a PubSub node in [XEP-0039] format.

The node defaults to `stats` but can be changed with the option
`pubsub_stats_node`.

``` lua
Component "pubsub.example.com" "pubsub"
modules_enabled = {
    "pubsub_stats";
}
pubsub_stats_node = "statistics"
```
