Bug 1070173 - Add '-v' option for oo-admin-ctl-tc to turn verbose output

This will change the output in this way:

```
# oo-admin-ctl-tc status 5347ce3cb60aa6709f000001
Bandwidth shaping status: 
tc is active for the user 5347ce3cb60aa6709f000001 [OK]
```

```
# oo-admin-ctl-tc status 5347ce3cb60aa6709f000001 -v
Bandwidth shaping status: 
tc is active for the user 5347ce3cb60aa6709f000001

```

The verbose option is optional and it can be used in other commands as well (if we would need to).
