Create queues documentation table.

[sergiitk]

A boilerplate queues documentation.

[deezone]

Add:

• Exchange column
• adjust column order to reflect the typical flow of messages:

| Producers | Exchange | Queue | Consumers | Description |

Should I keep the queues list?

[deezone]

This is an example of one row with only one of many queues connected to the transactionalExchange:

| Producers                                                   | Exchange                      | Queue                                  | Consumers                                              | Description                                             |
| ----------------------------------------------------------: |:-----------------------------:|:--------------------------------------:| :----------------------------------------------------: | :-----------------------------------------------------: |
| Phoenix                                                     | transactionalExchange (topic) | transactionalQueue (*.*.transactional) | mbc-transactional-email                                |                                                         |

| -> campaign reportback (campaign.report_back.transactional) |                               |                                        |                                                        |                                                         |

Perhaps the queue list should be broken down as their own table by exchange?

Merging this version so @DeeZone can make his changes to the structure, which is a little off.
