Introduce

sysstat implement in Golang. include iostat and mpstat.

Don't have sysstat tool in many arm linux, so do this project, you can use it immediately.

How to use?

1. go get github.com/DoLolitingyu/goiostat
2. iostat.GetData()
3. mpstat.GetData()

How's the effect? With iostat cmd?

You can run iostat_test.go to verify this.

99.9999999% close you use iostat cmd. Very small errors are also due to timing statistics, and the commands themselves are not exact.
