terry-xiaoyu 6ad65d587e feature(properties): add properties in message header
1. Add MQTT5.0 properties when invoking the hooks.

- Add a new key `properties` into the message header:

  We used to put all of the properties into the `#message.headers`:

  ```erlang
  #message{headers = #{'User-Property' => {<<"reason">>,<<"normal">>},
                       'Message-Expiry-Interval' => 60,
                       allow_publish => true}
  ```

  I put them instead under a single key:

  ```erlang
  #message{headers = #{properties =>
                        #{'User-Property' => {<<"reason">>,<<"normal">>},
                          'Message-Expiry-Interval' => 60},
                       allow_publish => true}
  ```

  Note that the column `properties` may contain all the properties for
  Publish and Will messages.

- Add `disconn_props` into the `Channel.conninfo`

- Add `puback_props` also into the message header:

  ```erlang
  #message{headers = #{puback_props =>
                        #{'User-Property' => {<<"reason">>,<<"normal">>}},
                       allow_publish => true}
  ```

2. Change the data type of `#message.headers` and `#message.flags` to map.

   It used to support `undefined`.
