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.

The nova api db need to be synchronized as well.

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)
