Connection handler for Amazon ES with dependency injection
---

Makes elasticsearch-js compatible with Amazon ES. It uses the aws-sdk to make signed requests to an Amazon ES endpoint.
Define the Amazon ES config and the connection handler
in the client configuration:

``javascript
var es = require('elasticsearch').Client({
hosts: 'https://amazon-es-host.us-east-1.es.amazonaws.com',
connectionClass: require('http-aws-es')(AWS),
amazonES: {
region: 'us-east-1',
accessKey: 'AKID',
secretKey: 'secret'
}
});
`

Alternatively you can pass in your own AWS Credentials object.
This is particularly useful if running on AWS Lambda, since the appropriate credentials are already in the environment.

`javascript
var myCredentials = new AWS.EnvironmentCredentials('AWS'); // Lambda provided credentials
var es = require('elasticsearch').Client({
hosts: 'https://amazon-es-host.us-east-1.es.amazonaws.com',
connectionClass: require('http-aws-es')(AWS),
amazonES: {
region: "us-east-1",
credentials: myCredentials
}
});
