Title: Added --version/-v option to 'sti', 'gear' and 'switchns'

The 'version' string is common for all command line components and the format should be same as docker use:

```
→ sti --version
sti version alpha3, build 178db29
```

The 'alpha3' is the latest 'git tag' and the build is current HEAD short ref.
