Title: Add configuration for Amazon MWS host

Amazon has different hosts for services depending on country. For example, from UK MWS services host is: https://mws.amazonservices.co.uk.
I added just a simple field to configure it. If host is not provided endpoint should use default one, which is https://mws.amazonservices.com.
