    Add a fail_on_undefined flag to the template and template_from_string methods.

    swallowing it.

    Optionally fail task on undefined variables

    This patch introduces a new configuration option called
    error_on_undefined_vars, which defaults to false.

    If this option is set to true, then a task which has unevaluated
    variables in its arguments will fail instead of running. Output looks
    like this:

        TASK: [set rabbitmq password] *************************************************
        fatal: [10.20.0.7] => Undefined variables: rabbitmq_user, rabbitmq_password

Allow to use ansible_ssh_user variable in `sudo_user` or `when` clauses

Docs: consistently format playbook EXAMPLES

Display default value in prompt when using vars_prompt

now mount/unmount binaries are searched for instead of hardcoded
