add a "vmstat" agent to the maven activemq performance plugin so we can track the CPU, IO,
RAM use on the machine we are running the test on
--------------------------------------------------------------------------------------------------------------------------------------------

         Key: AMQ-744
         URL: https://issues.apache.org/activemq/browse/AMQ-744
     Project: ActiveMQ
        Type: Improvement

  Components: Performance Test  
    Reporter: james strachan
 Assigned to: Adrian Co 
     Fix For: 4.1


When running a performance test it would be good to spawn off a process to run 'vmstat' which
works on linux and solaris (the flags may differ etc) which outputs the amout of CPU use in
system/user code and how much is idle together with RAM & IO numbers.

I'd be good to include in each snapshot whatever vmstat numbes we can find so we can see how
the box was doing as the test was running.

e.g.

<sample index="5" ... >
<machine cpuSystem="50" cpuUser="25" cpuIdle="25" ram="44" io="1000"/>
</sample>

Note that we may wanna make a few different machine monitoring agents using different tools
- so lets make it pluggable - let 'em write whatever XML they can - though we should be able
to get linux and solaris done (linux only would be fine for now)

To call vmstat we'll need to do a System.exec() then parse the results etc
