gnocchi when configured with swift will require keystone
to be available to authenticate to migrate to v3. At this
step keystone is not available and gnocchi upgrade fails
with auth error. Instead start apache in step 3, start
apache first and then run gnocchi upgrade in a separate
step and let upgrade happen here.

The default path if the operator does nothing is to keep the
sahara services on mitaka to newton upgrades.
If the operator wishes to remove sahara services then they
need to specify the provided major-upgrade-remove-sahara.yaml
environment file in the stack upgrade commands.
The existing migration to ha arch already removes the constraints
and pcs resource for sahara api/engine so we just need to stop
it from starting again if we want to remove it.
This adds a KeepSaharaServiceOnUpgrade parameter to determine if
Sahara is disabled from starting up after the controllers are
upgraded (defaults true).
Finally it is worth noting that we default the sahara services
as 'on' during converge here in the resource_registry of the
converge environment file; any subsequent stack updates where
the deployment contains sahara services will need to
include the -e /environments/services/sahara.yaml environment
file.

tripleo-heat-templates/extraconfig/tasks/major_upgrade_controller_pacemaker_2.sh
has the following code:
...
check_resource mongod started 600
if [[ -n $(is_bootstrap_node) ]]; then
...
tstart=$(date +%s)
while ! clustercheck; do
sleep 5
tnow=$(date +%s)
if (( tnow-tstart > galera_sync_timeout )) ; then
echo_error "ERROR galera sync timed out"
exit 1
fi
done
# Run all the db syncs
cinder-manage db sync
...
fi
start_or_enable_service rabbitmq
check_resource rabbitmq started 600
start_or_enable_service redis
check_resource redis started 600
start_or_enable_service openstack-cinder-volume
check_resource openstack-cinder-volume started 600
systemctl_swift start
for service in $(services_to_migrate); do
manage_systemd_service start "${service%%-clone}"
check_resource_systemd "${service%%-clone}" started 600
done
"""
The problem with the above code is that it is open to the following race
condition:
1) Bootstrap node is busy checking the galera status via cluster check
2) Non-bootstrap node has already reached: start_or_enable_service
rabbitmq and later lines. These lines will be skipped because
start_or_enable_service is a noop on non-bootstrap nodes and
check_resource rabbitmq only checks that pcs status |grep rabbitmq
returns true.
3) Non-bootstrap node can then reach the manage_systemd_service start
and it will fail with stuff like:
"Job for openstack-nova-scheduler.service failed because the control
process exited with error code. See \"systemctl status
openstack-nova-scheduler.service\" and \"journalctl -xe\" for
details.\n" (because the db tables are not migrated yet)
This happens because 3) was started on non-bootstrap nodes before the
db-sync statements are complete on the bootstrap node. I did not feel
like changing the semantics of check_resource and remove the noop on
non-bootstrap nodes as other parts of the tree might rely on this
behaviour.

We call gnocchi-upgrade to make sure we update all the needed schemas
during the major-upgrade-pacemaker step.
We also make sure that redis is started before we call gnocchi-upgrade
otherwise the command will be stuck in a loop trying to contact redis.

After a successful upgrade to Newton, I ran the tripleo.sh
--overcloud-pingtest and it failed with the following:
resources.test_flavor: Not all flavors have been migrated to the API database (HTTP 409)
The issue is the fact that some tables have migrated to the
nova_api db and we need to migrate the data as well.
Currently we do:
nova-manage db sync
nova-manage api_db sync
We want to add:
nova-manage db online_data_migrations
After launching this command the overcloud-pingtest works correctly:
tripleo.sh -- Overcloud pingtest SUCCEEDED

This commit does the following:
1. We now explicitly disable/stop and then remove the resources that are
moving to systemd. We do this because we want to make sure they are all
stopped before doing a yum upgrade, which otherwise would take ages due
to rabbitmq and galera being down. It is best if we do this via pcs
while we do the HA Full -> HA NG migration because it is simpler to make
sure all the services are stopped at that stage. For extra safety we can
still do a check by hand. By doing it via pacemaker we have the
guarantee that all the migrated services are down already when we stop
the cluster (which happens to be a syncronization point between all
controller nodes). That way we can be certain that they are all down on
all nodes before starting the yum upgrade process.
2. We actually need to start the systemd services in
major_upgrade_controller_pacemaker_2.sh and not stop them.
3. We need to use the proper bash variable name
4. Use is_bootstrap_node everywhere to make the code more consistent

Currently we do not disable openstack-cinder-volume during our
major-upgrade-pacemaker step. This leads to the following scenario. In
major_upgrade_controller_pacemaker_2.sh we do:
start_or_enable_service galera
check_resource galera started 600
....
if [[ -n $(is_bootstrap_node) ]]; then
...
cinder-manage db sync
...
What happens here is that since openstack-cinder-volume was never
disabled it will already be started by pacemaker before we call
cinder-manage and this will give us the following errors during the
start:
06:05:21.861 19482 ERROR cinder.cmd.volume DBError:
(pymysql.err.InternalError) (1054, u"Unknown column 'services.cluster_name' in 'field list'")

Currently we in major_upgrade_controller_pacemaker_2.sh we are calling
ceilometer-dbsync before mongod is actually started (only galera is
started at this point). This will make the dbsync hang indefinitely
until the heat stack times out.
Now this approach should be okay, but do note that when we start mongod
via systemctl we are not guaranteed that it will be up on all nodes
before we call ceilometer-dbsync. This *should* be okay because
ceilometer-dbsync keeps retrying and eventually one of the nodes will
be available. A completely clean fix here would be to add another
step in heat to have the guarantee that all mongo servers are up and
running before the dbsync call.

With commit fb25385d34e604d2f670cebe3e03fd57c14fa6be
"Rework the pacemaker_common_functions for M..N upgrades" we
accidentally removed some lines that fixed M/N upgrade issues.

This patch simply puts that code back without reverting the

This is the initial work to have a function that migrates a full HA
architecture as deployed in Mitaka to the HA architecture as deployed in
Newton where only a few resources are managed by pacemaker.
The sequence is the following:
1) We remove the desired services from pacemaker's control. The services
at this point are still running normally via the systemd service as
invoked by pacemaker
2) We do a "systemctl stop <service>" on all controllers for all the
services that were removed from pacemaker's control. We do this to make
sure that during the yum upgrade, the %post sections that call
"systemctl try-restart" do not take ages, because at this point during
the upgrade rabbit is down. The only exceptions are "openstack-core"
and "delay" which are dummy pacemaker resources that do not exist on
the system
3) We do a "systemctl start <service>" on all nodes for all the services
mentioned above.
We should probably merge this patch only when newton has branched as it
is very specific to the M/N upgrade.

For N we cannot assume services are managed by pacemaker.
This adds functions to check if a service is systemd or
pcmk managed and start/stops it accordingly. For pcmk,
only stop/disable on bootstrap node for example, whereas
systemd should stop/start on all controllers.
There is also an equivalent change to the check_resource
which has been reworked to allow both pcmk and systemd.

If "pcs cluster stop --all" is executed on a controller that
happens to have a VIP on the internal network, pcs may use the
VIP as the source address for communication with another cluster
node. When pacemaker is stopped this VIP goes away, and pcs never
receives a response from the other node. This causes pcs to hang
indefinitely; eventually the upgrade times out and fails.
Disabling the VIPs before stopping the cluster avoids this
situation.

The update and upgrade shell scripts were still referencing the
old openstack-keystone service which got removed with
Ie26908ac9bfc0b84b6b65ae3bda711236b03d9d4
Also removes kilo and liberty specific workarounds and config changes.

Since swift isn't managed by pacemaker we need to manually (systemctl)
stop and start the swift services. This moves the duplicate blocks for
start/stop into a common function (we already include that
pacemaker_common_functions.sh here so may as well)
