help functions for aws lambda

An effort to enable single lambda handles functionally the same requests from different sources: console test, sns, sqs, api gateway and api invoke. It also addresses AWS lambda EMFILE issue.

The packages collects code and ideas from lambda-emfiles and aws-event. It includes few improvements and replaces both packages.
