feature: Add support for a AWS China Region API service

Hi, @einaregilsson !

Thanks for creating this tool to create Elastic beanstalk deployments.

I’d like to request a feature that allows the consumer to modify the awsApiRequest function options so that we can modify the host. For global regions this works fine as shown below:

https://github.com/einaregilsson/beanstalk-deploy/blob/ebe3476a4ce991d54336935e75e78dd9d86f9408/aws-api-request.js#L17

However in China, regions like cn-north-1 and cn-northwest-1 regions have their API endpoints pointing to ${service}.${region}.amazonaws.com.cn (Note the .cn TLD)

Since I needed this on a project for work, I was wondering if there’s a way to be able to implement this on your library. I’ll be happy to open a PR.

Ok, great, I’ll put it into the next release then!

Hi

Do you know if it’s only in Chinese regions that this is the case? If so I’d probably just put in code right in aws-api-request.js that checks if region starts with cn- and adds .cn to the hostname directly there. If it’s in more regions I might have to add a whole parameter for the hostname to the action.
