[sos-devel] [v2 PATCH 1/1] Add IBM PowerKVM policy

[Kamalesh Babulal]

Add support for IBM PowerKVM platform, by introducing PowerKVM policy.
It defines PowerKVM specific details/environment, for sos to validate
the environment and enable plugins to collect information while running
over PowerKVM. Patch also introduces PowerKVM plugin class which could
be used by plugins, when we add support for them individually later.
