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.

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.
