metrics-cpu-pcnt-usage.rb only samples CPU usage for 1 second #10

metrics-cpu-pcnt-usage.rb only samples CPU usage for a 1 second period, surely this should run for at least 1-5 minutes to provide meaningful data?

It looks like it would make more sense to just return raw values (converted to seconds) which could then be interpreted by comparison with the previous reading, like the disk metrics script does.

@lp0 well if we were sampling for 5 minutes then the check would need to have a really high interval (greater than 5 minutes) to prevent multiple from running at the same time. I generally would use the interval + occurrences to make sure that people are not being alerted with super short lived spikes.
