1212e09ffd Adding the APIMetricsRegistry the metric factory
The MetricsRegistry in yammer used to create metrics and register them
in the JMX.

The APIMetricsRegistry extends the functionality by accepting a URL
that the API will perform to retrieve the relevant data, it also creates
the API version of each of the requested Metric (i.e. APIMeter,
APICounter or APIHistogram)

dd2d50a45c Overriden the Metric data collection
Three of the Metric in the yammer library are based on data that is
pushed to them: Counter, Histogram and Meter.

This patch modify the specific functionality by inherit the original
Meter, keeping its functionality and API, and modify the way the data is
collected.

For Counter: A call to count will be implementing by calling the API to
retreive a value.

For Meter: A call to count will be implementing by calling the API to
retreive a value, similiar to count, but the timer aspect of the Meter
remains the same.

For histogram: Histogram uses an internal sample container. To mimic the
behaviour, a call to any of the historgram get functionality will update
the sample container first. A timestamp of the last update limits the
number of updates that will be done by the histogram.
