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+.

The kolla_toolbox Ansible module executes as-hoc ansible commands in the
kolla_toolbox container, and parses the output to make it look as if
ansible-playbook executed the command. Currently however, this module
sometimes fails to catch failures of the underlying command, and also
sometimes shows tasks as 'ok' when the underlying command was changed.
This has been tested both before and after the upgrade to ansible 2.8.

This change fixes this issue by configuring ansible to emit output in
JSON format, to make parsing simpler. We can now pick up errors and
changes, and signal them to the caller.

This change also adds an ansible playbook, tests/test-kolla-toolbox.yml,
that can be executed to test the module. It's not currently integrated
with any CI jobs.

Note that this change cannot be backported as the JSON output callback
plugin was added in Ansible 2.5.

module_name is required for kolla_toolbox,but this module does
not check this argument.

This patch increases the default timeout for
the kolla_toolbox ansible module when talking
with the docker API from the default 60 to 180 secs.

This is required on slower deployments,
specially when bootstraping an environment and fernet
tokes are in usage. For faster deployments this will
be harmless, but for slower deployments this would be
beneficial.

The pypi package 'docker-py' [1] has been renamed to 'docker' [2].
It is better to move to the new 'docker' package because the old
package will be deprecated and all the new features will go into
the new package only.

Package 'docker' has been added to requirements [3]. The old
package 'docker-py' is still allowed to be in the global requirements
during the transition period but it should be removed after all or
most of the projects finsih the migration.

When docker-py is newer than docker daemon following
APIError may be raised:

client is newer than server (client API version: 1.24, server API version: 1.22)

So it's better to pass api_version='auto' to docker client,
so client will discover suitable version if not specified.

docker-py 2.0.0 is released with renaming docker.Client to
docker.APIClient. and with a new python package name "docker" rather
than "docker-py".
This patch support docker and docker-py packages.

There is inconsistent use of either `/usr/bin/python` or
`/usr/bin/env python`. This makes for unexpected results when a
user might be using a virtualenv.

docker engine 1.10 and docker engine 1.12 have different response for
list containers. Use status=running filter instead. It is provided by
all docker version.
