Include resourcePath and httpMethod fields in event.requestContext
Include resourcePath and httpMethod fields in event.requestContext

Events sent by the real AWS API Gateway have 'resourcePath' and 'httpMethod' as properties
of 'requestContext'. They duplicate the values of 'resource' and 'httpMethod' already present
one level above. See the docs here:

http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-set-up-simple-proxy.html#api-gateway-simple-proxy-for-lambda-input-format

Some libraries for implementing Lambda functions (in our case, we use claudia-api-builder)
rely on these fields being present. This patch adds these fields to the events generated
by serverless-offline.
