Changed the IO, Disk and Network classes to not use a subprocess. They now use psutil to get the metrics. Also, changed the linux system metrics classes to subclass the AgentCheck class instead of the old-style Check class. Added additional configuration and changed monasca-setup to support that. Fixed some Python 2.6 incompatible string formatting issues. Change-Id: I1f8b65bf48e48e2c598aa4950c194fbae2f9e337
