Not only match`/docker/`, but also `docker-` followed by a hex-id.

There is an old PR that shows a great use case for having a different
set of states for the server module. Before the other modules start
being in real use, pull this out so that we don't get ourselves into a
pickle.
It's up to the module using the set_fs_attributes*/set_mode* methods to
specify the filename of the destination of the symlink if that's really
the file that should be modified.
Half of the fix for:
https://github.com/ansible/ansible-modules-core/issues/778
It turns out that this can actually already be handled by the existing
auth plugin framework and does not need its own parameter. Remove before
it sees usage and causes confusion.
Incoming cloud config for OpenStack is complex due to plugins and
deployer choices. Rather than having the logic spread all over the
OpenStack modules, centralize it in the module_utils code.
I have a host which started to fail while gathering facts after the addition
of expanded memory facts in PR #9839:

KeyError: 'swapcached'
My problem host doesn't have SwapCached in /proc/meminfo. It may be better to
set defaults for these keys, since the values provided by /proc/meminfo can
change from version to version.
