Robin Gong 40228411d7 feat(example-mqtt): new MQTT heartBeat broker and client examples (#9336)
Motivation:

Recently I'm going to build MQTT broker and client based on Netty. I had MQTT encoder and decoder founded, while no basic examples. So I'm going to share my simple heartBeat MQTT broker and client as an example.

Modification:

New MQTT heartBeat example under io.netty.example/mqtt/heartBeat/.

Result:

Client would send CONNECT and PINGREQ(heartBeat message).
  - CONNECT: once channel active
  - PINGREQ: once IdleStateEvent triggered, which is 20 seconds in this example
Client would discard all messages it received.
MQTT broker could handle CONNECT, PINGREQ and DISCONNECT messages.
  - CONNECT: send CONNACK back
  - PINGREQ: send PINGRESP back
  - DISCONNECT: close the channel
Broker would close the channel if 2 heartBeat lost, which set to 45 seconds in this example.
