Provide a way to override or extend the Statsd module

[linusthe3rd]

It would be nice if consumers of cliquet could override or wrap the statsd module so they can use a different statsd implementation (such as datadog) or inject their own metadata into statsd calls.

For example, in my use case, we utilize datadog to track our metrics, which is compliant with the statsd protocol, but extends the API to introduce the concept of "tags". My team uses tags to inject extra metadata into metrics, such as values pulled in from custom internal HTTP headers.

It would be nice if I could modify the statsd module to utlize datadog and extend the logic to automatically inject other metadata into the metric.

Hello @strife25, thank you for your issue.

First, pluggability like that is totally within the scope of Kintocliquet. We did it for the cache backends, the permissions backends and the storage backends so if you need it we can do it for the stats backend.

The code is almost ready for it: https://github.com/mozilla-services/cliquet/blob/master/cliquet/statsd.py

We would need to:

• [ ] let you choose the client class from the config
• [ ] Define the Datadog client.

Can you show us an example of how you use tags? Would tags be something like the bucket/collection and record IDs ?

@Natim you can see how @tarekziade used tags in https://github.com/mozilla-services/absearch/pull/19/files

I would definitely be in favor modularizing a bit the code from cliquet.statsd to specify it from configuration.

Ok that's nice also we need to agree on the tags we want for Kinto right?
