mod_measure_process: Report the enforced limit The soft limit is what the kernel actually enforces, while the hard limit is is how far you can change the soft limit without privileges. Unless the process dynamically adjusts the soft limit, knowing the hard limit is not as useful as knowing the soft limit. Reporting the soft limit and the number of in-use FDs allows placing alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

Description
============

This is an experimental module that aims to identify the different
devices (technically clients) that a user uses with their account.

It is expected that at some point this will be backed by a nicer protocol,
but it currently uses a variety of hacky methods to track devices between
sessions.

Usage
=====

``` {.lua}
modules_enabled = {
    -- ...
    "devices",
    -- ...
}
```
