Update for prepare_role_for_ha_with_haproxy API change
Fix race-condition of post-install in HA setups

Make sure the post_install_conf recipe is only executed on a single node in a
HA setup. To avoid multiple nodes racing over the network/router creation.

Run once neutron-db-manage check_migration to do the db_sync

Neutron is actually magic and can perform that by itself, except that in
the HA case, concurrent neutron instances try to do it at the same time,
and fail. That's why we need to manually do it first.

Also, we only do it the very first time (and we remember that through an
attribute).

Fix the schema migration that adds the neutron-l3 role

The nodes that had the "neutron-server" role assigned before also need
"neutron-l3" after upgrading the schema. Otherwise they end up with an
incomplete run_list. (bnc#875022)

Configure Nova Notifier

Neutron uses a new notification mechanism for telling
Nova when vif's have been plugged or unplugged. Without
this certain network setup operations simply time out.
ha: Fix initial DB sync

The initial database sync for neutron doesn't occur with
"neutron-db-manage check_migration"; it occurs when the neutron-server
daemon starts. This is perfect for non-HA, but breaks for HA since
cluster members will run this concurrently and will fail to execute the
db migrations all at the same time.

To make this work, I can't think of any other way than starting once
neutron-server (to get the db sync) and then stopping it, to then hand
over all of this to pacemaker. We only do this for HA (since it's
useless without HA) and we only do this the first time on the cluster
founder (like before, for the old code we thought would work).
