Dan Smith c07046edee Make n-net refuse to start unless using CellsV1
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.
