Statsd counter for user agents.

Browse Source 
We want to log the usage of the various API clients we have so that we understand when they can be cycled.

To this end we are going to count usage in statsd.

All notify clients have a suer agent, of the format: NOTIFY-API-{LANGUAGE}-CLIENT/version.number

For example, NOTIFY-API-PYTHON-CLIENT/3.0.0

We convert that into a statsd/graphite friendly string of the format: notify-api-python-client.3-0-0

So we can subdivide on client and client version on our dashboards.

Present but unknown User agents are records as "non-notify-user-agent"

Missing are presented as "unknown"
