Http input plugin doesn't hornor parser time_format in batched scenario

[yantang-msft]

Fluentd Version: 1.2.1
Environment: Windows 10
Configuration:

<source>
  @type http
  port 8887
  <parse>
    @type json
    time_format %iso8601
  </parse>
</source>

<match **>
  @type stdout
</match>

Problem:
Running this command curl -X POST -d '[{"foo":"bar", "time": "2018-06-12T18:35:48.1488850Z"},{"abc":"def"},{"xyz":"123"}]' http://localhost:8887/app.log gives me this error can't convert String into an exact number

It's very similar to this issue #2018 I reported earlier. The difference is this time it's the time_format parameter instead of the time_key.
With this fix #2025, I can workaround the issue by setting time_key to nil, so it's not an urgent for me. But still it would nicer if the time_format parameter is also supported in batched scenario.

I am seeing this too. Sending a single JSON event works, but sending a JSON array with multiple events triggers this error
