update help string for messaging_urls
We have come across problem when we follow the example of
messaging_urls, the credentials for multiple hosts fall back to
default except the first host. This patch updates this option's
help string to make it clear and right.
1. change 'transport' to 'rabbit' in example
transport is a term in oslo.messaging, it is not a real type of
oslo.messaging driver, as for an example, we should use a real
one.
2. add credentials for each node
when there are multiple nodes specified in url, each node should
have its own credentials, oslo.messaging doesn't support using
first one for all.[1]
3. add explaination for the usage scenario
normally, there is no need to set the messaging_urls, it is
useful when we have dedicate messaging nodes for each service.
