This reverts commit c07046edeee562142c90aa3cadd4bdc47b0a15da.
Trove's CI jobs don't currently work with Neutron due to
bug 1629133 so this is a temporary revert until the Trove CI/infra
networking situation gets sorted out. We have agreement from
the Trove PTL to revert this revert after the o-2 milestone on
2016/12/15.

Related-Bug: #1629133
At the Barcenlona summit, we discussed disabling n-net everywhere as a
precursor to removal. The only exception for using n-net is as required
for CellsV1 users, which require it as the only out-of-the-box supported
networking option.
We will remove this check and n-net entirely when those users have a
migration path to neutron and cellsv2.
