    Clarify introspection failed attempt log message

    This change clarifies that an introspect attempt failed, implying that
    a future attempt might succeed.

    This is part of a fix for transient failures when calling
    ironic-inspector leading to logging indicating introspection failed
    when it actually succeeded.

    The layout of the message is also changed slightly to make Kibana
    searches for failures easier.
