----------------------------------

    Attachment: 0001-BOOKKEEPER-614-Generic-stats-interface-which-multipl.patch

Implemented as a separate module, which bookkeeper-server pulls in. hedwig-server and hedwig-client can pull it in later as well.

There's an example of how this will be used here[1].

> Currently we collect stats though JMX. Adding a new stat to JMX is cumbersome, and reading the stats out of JMX is painful if you're not on the same machine. As a consequence, we aren't measuring a fraction of the stuff we should be.
> There are a couple of nice stats packages out there, such as twitter-stats[1] and codahale metrics[2], which would make collection of stats much easier.
> This JIRA is to provide a generic interface, which a metrics backend can be plugged into.
