when php use not common locale (RU for example) simple
convertion float to string may look like
and udp request send strings like this
12,2323|ms and statsd can't correctly parse such strings
* allow overriding statsd host and port, by means of
STATSD_HOST and STATSD_PORT environment variables
* lowercase non-environment variables. that's a good convention
* rename 'statsd' variable to 'host'
