Update document for Huawei cinder volume driver

Huawei FC driver and HVS storage system driver were merged into
Havana. So this patch updates configuration guide for the changes.

Use consistent RabbitMQ settings across guide.

Use consistent values for rabbit_host, rabbit_userid, and
rabbit_password across the guide. Previously there were a number of
variations, particularly of the host and password values.

In a subsequent patch I intend to cover off the fact that RabbitMQ
is installed/configured in at least two locations. I may depending
on feedback also end up adding an instruction to set the guest
user's password in which case a further update to rabbit_password
will be required.

I think just getting the initial values to base this work on consistent,
as I am proposing in this patch, is a good start.

Where programlisting elements that were touched use "bash" as the
language I have also flipped them to "ini".

Use consistent address for Qpid

Consistently use the controller host name for Qpid. Files from
the old basic install guide which are slated for removal were
left untouched.

Removed FIXME on RabbitMQ setup.

Installing the RabbitMQ packages on Ubuntu results in the service being
started automatically and a guest user (with password guest) being
created. No additional setup is required (at least for a basic setup).
