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).

Introduction
============
This module attemtps to provide a storage driver that is really multiple
storage drivers. This could be used for storage error tolerance or
caching of data in a faster storage driver.
Configuration
=============
An example:
``` {.lua}
storage = "multi"
storage_multi_policy = "all"
storage_multi = {
"memory",
"internal",
"sql"
}
```
Here data would be first read from or written to [mod\_storage\_memory],
then internal storage, then SQL storage. For reads, the first successful
read will be used. For writes, it depends on the `storage_multi_policy`
option. If set to `"all"`, then all storage backends must report success
for the write to be considered successful. Other options are `"one"` and
`"majority"`.
