Andrey Pavlov 53eaa64263 Formatting and mounting methods changed for ironic
Currently only cinder volumes can be formatted and mounted.
This patch provides an ability of formatting and mounting
any attached storage devices. Also storage_paths method was
moved from node group objects to instance and corresponding
fixes in plugins was made.
