In order to test NGS compatability and generally move the state forward
we need to be able to wire in switch simulators.
This is *not* intended to be run in CI, due to known performance issues.
This first pass hooks up Dell Force10 switches with OS version 9.13, and
does so we can configure the switch as part of the setup.
This makes the prior behavior of configure-vm.py and the VM templates
to be able to execute as it did before
I0ef1ad1b2e50cb26839c618a1367704d51ed8a4d to enable the simulator attachments
because we can't exercise network switch simulators with dynamic
post-vm start network attachments, becuase the attachment to the switch sim
must be done in advance of switch VM launch.
