Add support for smartpqi

Add support for smartpqi/arcconf RAID adapters on Linux

The smartpqi driver for Adaptec/Microsemi RAID controllers uses a cli tool called arcconf. Add support modeled after the existing MegaRAID/storcli structures and implement the RAID Controller interface introduced to abstract the specific RAID adapter for the linux system.

• Did not implement the Caching mechansim, repeated invocations do not have any significant impact on system, 5 minute timeout seems quite long to wait for RAID device changes which happen immediately after issuing arcconf commands.

• Refactored how linux package looks up disks to see if they belong to a RAID adapter to prevent import loops.

• Added tests for arcconf for the interface commands parsing output collected from systems with smartpqi driver and card

• Added smartpqi to the demo program

Thanks - it looks good to me. Did you want to rebase or merge as is (with or without the 3 error messages updated)?

I'll address your comment and rebase/squash into 3 commits (and fix the lint error I somehow missed)
