future PR once raw GetSpec() is complete.

Skip influxdb tests for now.
Features:
Added Network Stats to Container Info. It still not exposed via the HTTP UI.
Bug fixes:
1. Modified docker handler to use libcontainer.GetStats instead of quering the fs package.
2. cAdvisor will not stall if any of its core operations fail.
3. cAdvisor will safely ignore any inactive or leaked docker containers. When containers are leaked cgroup state exists but docker is not aware of them.
Adding utils package
Fix raw cgroups handler.
Fixed bugs introduced in previous patches.
