Since the filter list contains hosts, passing that back to list_hosts()
in the inventoy causes issues when the hostname is an IPv6 address
(with :'s interpreted as group unions). Since we already have the list
of hosts, we should not need to pass that back through inventory a
second time.

Fixes #7446

Fix skip dir inventory extensions

Also added some error handling to the fetch_url() call in the
apt_repository module, so that failures to look up the PPA info
are properly handled.

Fixes #7322

The ssl cert check will now respect the http and https proxy

embedded, in which case basic auth will be used to connect to the
proxy server.

docker: fix targetting images by name

If the module directory is not writable/executable to the current user
(most likely because of a sudo to a non-root user), the ssh_wrapper
will be created in the default location for mkstemp() calls. To facilitate
the deletion of these new files, a new mechanism for cleaning up files
created by the module was also added.

Fixes #7375

Fix known_hosts.py to work on older versions of python

When we hard-link a file, and the link path already exists, give the link path in the error message instead of the source

When a symlink fails because the path already exists and force=no, we should output path in the error message instead of source.

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
chown() and where the source and destination for the atomic_move
are on that remote file system.

Fixes #7372
