Comment 4 for bug 1785086

speaking about the documentation there are few errors, or let's say imprecisions
https://docs.openstack.org/nova/stein/reference/rpc.html

1.
```
Nova uses Kombu to connect to the RabbitMQ environment. Kombu is a Python library that in turn uses AMQPLib,
```
AMQPLib is a nodejs lib, the correct one is `py-amqp`

2.
```
a library that implements the standard AMQP 0.8
```
AMQP 0.9.1 not AMQP 0.8

3.
Nova uses Kombu to connect to the RabbitMQ ...
```
should be:
```
Nova uses olso.messaging
```

At this point I'd link to olso messaging documentation,else is redundant information that can cause entropy.

It is not correct ( in my opinion ) to report all this info. That is generic info and not specific to nova.
