root fe5bcccfe2 Add hpssa module to proliantutils

This commit introduces the hpssa module. The module has
the ability to parse the current raid configuration and
hardware details of the server. It also has a manager
which has ability to create/delete/get raid configuration.

For now, create is limited to machine-dependent configuration.
Each logical disk to be created will require the controller
and physical disks to be used.

Implements: blueprint hpssa-support
