Review request for mesos, Benjamin Hindman and Vinod Kone.


Changes
-------

non-virtual meter methods


Description
-------

This add metering into the statistics model. The metering was inspired by jie's 
monitoring reviews.

We'll need to compute metered data on top incoming raw data. The challenge is 
that some meters will require previous data:
For example:
1. cpu_time = 10 @ time 10;
2. cpu_time = 20 @ time 20; --> cpu_usage = 1.0 (100%) this is 20-10 / 20-10
3. cpu_time = 25 @ time 30; --> cpu_usage = 0.5 (50%) this is 25-20 / 30-20


This addresses bug MESOS-324.
