Use one RabbitMQ services instead of multiple

[Leminkay]

The queue name allows one queue service to be used to create parallel flows to different runners.
Currently, the queue name is hardcoded in the config.py, which makes it impossible to use the same queue service for multiple runners.

the name is set here

vyzzer/fuzz/runners/runner_api.py

Line 138 in 33c81cd

self.queue_name = 'queue3.10'

now. So it's probably supposed to be generated if it's not set in the config
