VM attaches to the wrong virtual switch in Hyper-V

[akarasulu]

Vagrant creates a proper vagrant-subutai virtual switch to bridge the VM to the network however the VM does not use it and is instead attached to Default Switch. This creates severe problems because of MTU issues with p2p which in itself needs to be solved.

1. @jadilet please work with @crioto to make sure the NAT configuration through the Default Switch works properly with P2P.
2. Make sure we use the vagrant-subutai switch to bridge instead of using the Default Switch
