Steps to reproduce:
1. Deploy FUEL/MOS 8.0 environment in any configuration
2. Try to get stack list

Observed result:
command won't be executed
Following error in heat-engine log:

Seems that at the beginning heat-engine successfully connected to AMQP server, but lately it started to send requests to invalid url.

I found very strange set of heat-engine processes on the controller:
root@node-1:~# ps -aux | grep heat-engine

There are a few heat-engine processes which run without config file, so they use default amqp server ip and port. This processes were run be pcs.

It is not clear why there are another two heat-engine processes.
