splinter98 8293f546af Add support for MQTT server as a notification target (#4474)
This implementation is similar to AMQP notifications:

* Notifications are published on a single topic as a JSON feed
* Topic is configurable, as is the QoS. Uses the paho.mqtt.golang
  library for the mqtt connection, and supports connections over tcp
  and websockets, with optional secure tls support.
* Additionally the minio server configuration has been bumped up
  so mqtt configuration can be added.
* Configuration migration code is added with tests.

MQTT is an ISO standard M2M/IoT messaging protocol and was
originally designed for applications for limited bandwidth
networks. Today it's use is growing in the IoT space.

Eclipse Paho MQTT Go client
===========================
This repository contains the source code for the [Eclipse Paho](http://eclipse.org/paho) MQTT Go client library.
This code builds a library which enable applications to connect to an [MQTT](http://mqtt.org) broker to publish messages, and to subscribe to topics and receive published messages.
This library supports a fully asynchronous mode of operation.
Installation and Build
----------------------
This client is designed to work with the standard Go tools, so installation is as easy as:
```
go get github.com/eclipse/paho.mqtt.golang
```
The client depends on Google's [websockets](https://godoc.org/golang.org/x/net/websocket) package,
also easily installed with the command:
```
go get golang.org/x/net/websocket
```
Usage and API
-------------
Detailed API documentation is available by using to godoc tool, or can be browsed online
using the [godoc.org](http://godoc.org/github.com/eclipse/paho.mqtt.golang) service.
Make use of the library by importing it in your Go client source code. For example,
```
import "github.com/eclipse/paho.mqtt.golang"
```
Samples are available in the `cmd` directory for reference.
Runtime tracing
---------------
Tracing is enabled by assigning logs (from the Go log package) to the logging endpoints, ERROR, CRITICAL, WARN and DEBUG
Reporting bugs
--------------
Please report bugs by raising issues for this project in github https://github.com/eclipse/paho.mqtt.golang/issues
More information
----------------
Discussion of the Paho clients takes place on the [Eclipse paho-dev mailing list](https://dev.eclipse.org/mailman/listinfo/paho-dev).
General questions about the MQTT protocol are discussed in the [MQTT Google Group](https://groups.google.com/forum/?hl=en-US&fromgroups#!forum/mqtt).
There is much more information available via the [MQTT community site](http://mqtt.org).
