[engine] output queue name for agent

[Steve McLellan]

Murano engine defines the agent output queue name (for the listener) in muranoapi/engine/system/agent_listener.py:

    self._results_queue = str('-execution-results-%s' % name.lower())

This can (easily) result in name conflicts between users (or even for the same user in some circumstances). There is a more general authentication problem with the agent queues that will be addressed in a blueprint, but i suggest for now using the environment object id in the same way as when the instance agent queues are set up.

Environment ID cannot be used because it can be any string (for example UUID with dashes) and not every string can be Heat stack name (for example it cannot contain dashes)
