This patch will allow moving neutron from using the nsx_v3 plugin to the nsx_p plugin.
This includes:
- admin utility to move all resources to the policy api:
nsxadmin -r nsx-migrate-t2p -o import (--verbose)
This utility will:
-- Migrate all neutron used & created resource using the nsx migration api
-- roll back all resources in case it failed
-- post migration fix some of the policy resources to better match the expectation
of the policy plugin
- admin utility that will cleanup left overs in the nsx_v3 db:
nsxadmin -r nsx-migrate-t2p -o clean-all
(can be used, but everything should work without calling it as well)
- Some minor changes to the policy plugin and drivers to allow it to handle migrated resource
which are a bit different than those created with the policy plugin
-- Delete DHCP server config once a migrated network is deleted
-- Update LB L7 rules by their name suffix as their full display name is unknown
