Set http timeout to 30 mins.

[rc1]

By default aws only allows the http request 2 minutes to upload. This PR increases the limit to 30 minutes. It will also report when a request is being retried and including the reason why.

I was trying to upload 8megs at home. It was taking 8 minutes to report a fail. This was because it uploads for 2 mins, waiting for 1 min and attempts twice more.

Thanks.

Is 30 mins the max allowed, or an arbitrary number?
Would you mind adding tests for your changes?

Thanks for your contribution!

[rc1]

It's just an arbitrary number. There is no limit from amazon.

I'm not sure what the additional tests would be? This PR is not expositing any additional functionality.

[DeviaVir]

@rc1 I was thinking about two tests, one to see if aws.config.httpOptions.timeout is being set (correctly), and one that would test the retry functionality you've added.

[rc1]

To clarify, I've not added the retry functionality. It's doing that already. I'm am just logging the event to the console.

Being honest, I was just playing with a couple of free hours at home. I'd love to dig into the testing and figure it out... but I won't have time it the moment. Feel free to close.

@rc1 apologies, it was not my intention to over-complicate things or to make this repo seem unreachable. I definitely want this change in as it makes node-lambda more usable for a broader public. Let me take a moment to see what kind of tests make sense and I'll be sure to add them on top of your changes.
Again, much appreciated that you spent some of your free time on this project.

[rc1]

@DeviaVir no apologies needed. It is a bit lame on my part.

Ingoring this PR, it would be helpful to have either aws.config.httpOptions.timeout changed or changeable.
