This commit addresses a few shortcomings in the etcd service:
* Adding or removing etcd nodes required manual intervention.
* The etcd service would have brief outages during upgrades or
reconfigures because restarts weren't always serialised.
This makes the etcd service follow a similar pattern to mariadb:
* There is now a distiction between bootstrapping the cluster
and adding / removing another member.
* This more closely follows etcd's upstream bootstrapping
guidelines.
* The etcd role now serialises restarts internally so the
kolla_serial pattern is no longer appropriate (or necessary).
This does not remove the need for manual intervention in all
failure modes: the documentation has been updated to address the
most common issues.
Note that there's repetition in the container specifications: this
is somewhat deliberate. In a future cleanup, it's intended to reduce
the duplication.

Set the openstack exporter HAProxy backend server timeout to
``prometheus_openstack_exporter_timeout`` to ensure that scrapes
that take longer than haproxy_server_timeout don't timeout.

Since the CI is failing and there are no contributors working on fixing
this, we are deprecating the service.
Also mention other deprecations in the README.

docker_restart_policy: no causes systemd units to not get created
and we use it in CI to disable restarts on services.
Introducing oneshot policy to not create systemd unit for oneshot
containers (those that are running bootstrap tasks, like db
bootstrap and don't need a systemd unit), but still create systemd
units for long lived containers but with Restart=No.

This avoids the need to use a proxy, or some other means, to connect to
Prometheus. This is disabled by default and can be enabled by setting
enable_prometheus_server_external to true.

Kolla Ansible should deploy Glance and Cinder Backup with
S3 backend support working out-of-the-box.
The S3 backend had been re-introduced in Ussuri after being
deprecated around the Mitaka timeframe, and having some local
object storage options is nice for testing..

* Zun currently has a dependency on a combination of Docker and
etcd that is no longer installable (or supported) in newer
distros.
* These components are core dependencies of other systems and
vendoring them will be very painful.
* Work to update Zun past this is scheduled for the 'C' cycle.
* If Zun regains compatibility, backports to this series will be
considered.
