Since 0.11 Docker supports different networking modes (see docker run
--net). This commit add support for that to the ansible docker module.

This depends on
https://github.com/dotcloud/docker-py/commit/2d58351164eba01e30569f44a921d5aca40163ae

Fix known_hosts.py to work on older versions of python

Fixes #7405

Fixes #7385

Pass vars_files on to included playbooks too

Make sure the docker data has a "Names" field before using it

Merge branch 'file_new_dirs_perms' of https://github.com/bcoca/ansible into bcoca-file_new_dirs_perms

Fix env splitting in docker module

This is a corner case for remote file systems that don't support

are on that remote file system.

Fixes #7372

Merge branch 'pass-basedir-to-runner-on-setup' of https://github.com/ByteInternet/ansible into ByteInternet-pass-basedir-to-runner-on-setup

postgresql_user module documentation:  Clarify that the encrypted param must also be set.

Properly merge role conditionals in with pre-existing conditionals

ENV variable value could contain '=' (for example mysql://host/db?pool=10)

While the encrypted parameter's documentation clearly states that it needs to
be set, if you are focused on the password parameter's documentation, there's
nothing to draw your attention to the fact that encrypted may also need to be
set.

Retinafy favicon.ico

Fix grammar and value errors in cron documentation

Previously we assumed the shell on the target systems were 'sh'-
compliant when formatting environment variables preceding command
strings. This patch corrects that by basing the target shell type
on the DEFAULT_EXECUTABLE setting, which can be overridden on a
per-host basis using the inventory variable 'ansible_shell_type'.

Fixes #7352

Add documentation for required parameter name to quantum_subnet
