armando-migliaccio 070def25e5 Rename DB models and related resources for VMware NSX plugin
This patch also introduces a DB migration to update the
affected tables, and the enum type for those DB engines that
require it.

Additions made to existing migrations are needed to ensure
that green deployments using the new plugin name will apply
the migrations correctly.
