local devstack can not startup usinglocal.conf.example

[Dong Jun]

The error log[1] told me configure_neutron_after_post_config not found but it should not happen.
What I got so far seems that it is related to commit[2].
Looking at lib/neutron in devstack[3], if there were some some neutron services disabled, is_neutron_legacy_enabled returned false and sourcing neutron-legacy was skipped.
Did grenade not failed due to different handling with q-*, I guess so.

Either the local.conf.example should be adapted to neutron services or the override-defaults should be adapted to q services.

local.conf.example needs to be updated to enable neutron-api instead of q-svc.
also q-dhcp and q-meta also changed to neutron-dhcp and neutorn-meta.

But I haven't tested it personally. Can you please test it?

    devstack: update local.conf.example to use lib/neutron

    now networking-odl/devstack is using lib/neutron instead of
    lib/neutron-legacy. So update local.conf.example to adapt it.
