Subject: [PATCH] collectd: Configure the processes plugin

The *processes* plugin for collectd can be configured to monitor
additional information about specific processes.  By specifying one or
more `Process` or `ProcessMatch` directives in the plugin configuration,
collectd will start monitoring the listed processes in detail.

The `collectd_processes` Ansible variable can contain a list of
processes to monitor.  Each item must at least have a `name` property,
and may also have a `regex` property.  If the latter is present, a
`ProcessMatch` directive will be emitted instead of a `Process`
directive.
