add more user friendly cli utilities

[phillxnet]

I propose we add at least the following utilities to facilitate better dev and user diagnostics. These utilities could then be augmented by a series of report scripts.

• nano (see http://forum.rockstor.com/t/install-on-hp-dl360-g5-fails-to-detect-hardware-raid-solved/197/27)
• lsusb (in usbutils in base)
• lspci (in pciutils in base)
• a custom script to report the raw output of smartctl and our logs, tar.gz together ready for users to send for smart diagnostics issues, eg "rocksmart sda sdc", or if possible a "rocksmart all" see http://forum.rockstor.com/t/question-about-rockstor-install-with-issues-im-seeing/204

And although they can be installed if they are in the iso / installed system then in rescue mode / chroot env they are available.

Also to set drive power down times:-

• hdparm this way we can do eg

/sbin/hdparm -S60 /dev/sda

nano, lsusb, lspci, and hdparm are now all installed by default on testing version of 3.8-6 iso. Note that they are also included on the iso for use in the rescue mode. This is great, thanks @schakrava closing as I think the custom script to report raw output of a bunch of things deserves it's own issue / feature request.
