Merge "Remove /etc/hosts entries pointing hostname to localhost and prevent cloud-init to manage /etc/hosts"

cloud-init to manage /etc/hosts

1) Ubuntu includes a line in /etc/hosts that makes the local hostname and
nodename (if different) point to 127.0.1.1. This can break RabbitMQ,
which expects the hostname to resolve to the API network address.

2) The distribution might come with cloud-init installed, and manage_etc_hosts
configuration enabled. If so, it will override the file /etc/hosts from cloud-init
templates at every boot, which will break RabbitMQ.

This change fixes these issues.

Adds information on configuring consoles.

This ensures that failure of a single host fails the whole play at that
task. This can avoid confusing errors such as when the task
"Assert that the nodepool private IPv4 address is assigned" fails on one
host, causing subsequent errors on other hosts.

Note that this only affects the Zuul playbooks, not Kolla Ansible's
playbooks.

Currently, swift-proxy config uses hosts in the swift-proxy-server group
to generate the list of memcached servers. However, memcached is
deployed to hosts in the memcached group.

This change fixes the memcached_servers option for swift-proxy to be the
same as other services.

The idea is to factor out a role for deploying Nova related services
to cells. Since all deployments use cells, this role can be used
in both regular deployments which have just cell0 and cell1,
and deployments with many cells.

Since
https://opendev.org/openstack/kolla-ansible/commit/70b515bf1225e56b7df81677043d75be4bbb1ab4
was merged, we implicitly require Docker API version 1.25
(https://docs.docker.com/engine/api/v1.25/) to support passing
environment variables to docker exec. The version of docker we deployed
before the Docker CE upgrade was 1.12.0, which is Docker API version
1.24, and so does not support this. We get the following error:

    Setting environment for exec is not supported in API < 1.25

This change modifies the kolla_toolbox module to use the new JSON
method for parsing Ansible's output when Docker API 1.25 is available,
falling back to the old regex-based method otherwise.

This change can be reverted when we require a minimum Docker API version
of 1.25+.
