Matthew Oliver 093e41e0ef Add statsd configuration for swift
This adds the optional configuration options:
  - statsd_host
  - statsd_port
  - statsd_metric_prefix (defaults to inventory_hostname)
  - statsd_default_sample_rate
  - statsd_sample_rate_factor

Which can be defined under swift globally or on the server level.
The configuration will only be added if statsd_host is defined.
