The very first start of 'fireball mode', which uses ansible in SSH mode to deploy a ephemeral zeromq daemon (entirely optional) that is will die after
it is no longer used.  No key signing will be required.  At this point, development use only -- NOT complete.

Ignore failure of stop command if start succeeds with state=restarted

In some cases (see issue #1067) with state=restarted, a failure to stop
the service (which wasn't running) would appear to the module to be a
failure to restart the service even though it successfully started the
service.  This changes the behavior of the service module to focus
on the return code of the start command.  If the rc of stop is not
0 and the rc of start does equal 0, it considers the service
successfully restarted.  It then ignores the rc, stdout, and stderr
from the unsuccessful stop command.

2 improvements to delegate_to

Getting negative host pattern matching to work with external inventory

Give nice error message if destination directory doesn't exist 

Add 'pause' action plugin and support plugins skipping the host loop.

(same as commit 4caf85e3, but for
excluded hosts as well as subsets)

Fix a typo in the prompt code

This is unfortunately related to not being able to reuse the same code that was tested.

Add an only_if option to vars_prompt to make prompts conditional

Sometimes you may want to allow variables through host_vars or inventory, but prompt for a value if it is not set or if the value does not conform to something specific. This option allows you to specify when you want to offer a prompt.

This patch also moves check_conditional to utils, and adds an is_unset() function which is nicer to read:

    only_if: "not is_set('${var}')"

vs

    only_if: "is_unset('${var}')"

Modified 'ok' to 'changed' when a change has occured

Template the variable prompt to customize the message

We have a password-prompt for a configurable login name. Since we require to ask the password for this specific login, it is important to indicate what password needs to be prov ided on the prompt. So the prompt needs to be templated. That's what this patch does.
