Drop lib/neutron module
Module lib/neutron was introduced long time ago as new module to deploy
neutron. It was intended to replace old lib/neutron-legacy module. But
since very long time it wasn't really finished and used by anyone and
lib/neutron-legacy is defacto standard module used by everyone to deploy
neutron with devstack.
In [1] unfinished lib/neutron was deprecated and now it's time to remove
it from the devstack code.
This patch also renames old "lib/neutron-legacy" module to be
"lib/neutron" now.
Previously "old" lib/neutron-legacy module was accepting neutron
services names wit "q-" prefix and "new" lib/neutron module was accepting
services with "neutron-" prefix. Now, as there is only one module it
accepts both prefixes.
For historical reasons and to be consistent with old lib/neutron-legacy
which was widely used everywhere, services will be named with "q-"
prefix but both prefixes will be accepted to enable or disable services.
This patch also moves _configure_neutron_service function to be called
at the end of the "configure_neutron" after all agents and service
plugins are already configured.
