Pull #135

travis-ci

added the option to pass in credential settings

allows for using a different authentication mechanic like EXTERNAL for certificate only authentication without username/password
```
const settings = {
	connection: {
...
		certPath: "secrets/client.pem",
		keyPath: "secrets/client.key",
		credentials: amqp.credentials.external()
...
```
