Edit rescue procedure in the HTTP connection part

I am using out_http plugin in our service. it has been running in so many servers.
but, sometimes, Fluentd has been broken down(looks like freezing td-agent) because it occurred http connection error.
so, I researched this trouble, and I found it. and I edited rescue procedure in the HTTP connection part in your source.

could you please confirm my pull request?

thanks.


thank you for your response.

I think that it will be fine for me also.
could you please edit it?
