Vagrant fix

Wanted to try your method to install OpenStack but only have VirtualBox available to me at the moment. I've gotten a lot of it working now but is not completely without errors. 

```
./bin/run_vagrant.sh standard
```
I need to get this work next...
```
TASK: [cinder-volume | cinder volume group] ***********************************
failed: [compute1] => {"failed": true, "parsed": false}
invalid output was: SUDO-SUCCESS-dcpftkilzppyuyegxgrupnmesxdcavtv
/home/vagrant/.ansible/tmp/ansible-tmp-1406857372.92-244680026450599/cinder_volume_group:94: syntax error, unexpected $end, expecting keyword_end


FATAL: all hosts have already failed -- aborting
```
Honestly I found an example somewhere else and they were doing it this way. It may have been hanging because of the order originally. I move the br-int below 
```
 - service: name=neutron-openvswitch-agent state=started
```
I'll put back the old line 14 ->15  where the new 18 -> 21 is and test it again.
