    Remove 'ignore_errors: true' in favor of 'failed_when: false'

    This change removes the use of 'ignore_errors: true' because it causes deployers
    to see red output and a stacktrace, which traditionally means something is broken,
    even when the failure is known to have a fall back option or be intentional. This
    conversion will provide a generally cleaner interface.

    It should be noted that the 'failed' filter will still function normally. Tasks
    with the 'failed_when: false' option will still be marked as 'failed' in any
    registered variable. This change simply makes the output look cleaner.
