This is the first stage of the power management series. In order to be able to switch the CPU state or change the governor, we need a framework to access sysfs. As some bits can be reused, let's create a nova.filesystem helper module that will define read-write mechanisms for accessing sysfs-specific commands. Partially-Implements: blueprint libvirt-cpu-state-mgmt Change-Id: Icb913ed9be8d508de35e755a9c650ba25e45aca2
