API and CLI for CPU info

[tzach]

Linux users are used to go to /proc/cpuinfo for CPU related information, having compatible functionality for OSv will be useful.

Example below from Fedora 20

processor   : 2
vendor_id   : GenuineIntel
cpu family  : 6
model       : 69
model name  : Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz

cpu MHz     : 2294.686
cache size  : 3072 KB
