(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.
