API and CLI for CPU info

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
stepping    : 1
microcode   : 0x1
cpu MHz     : 2294.686
cache size  : 3072 KB
fpu     : yes
fpu_exception   : yes
cpuid level : 13
wp      : yes

clflush size    : 64
cache_alignment : 64
address sizes   : 40 bits physical, 48 bits virtual
power management:

dmtf.org define the following processor information:

Role : string
Family : uint16 {enum}
OtherFamilyDescription : string
UpgradeMethod : uint16 {enum}
MaxClockSpeed : uint32 {units}
CurrentClockSpeed : uint32 {units}
DataWidth : uint16 {units}
AddressWidth : uint16 {units}
LoadPercentage : uint16 {units}
Stepping : string
UniqueID : string
CPUStatus : uint16 {enum}
NumberOfEnabledCores: uint16 {E}
ExternalBusClockSpeed: uint32 {units}
Characteristics: uint16[] {E, enum}
EnabledProcessorCharacteristics: uint16[] {E, enum}
