[Bug 1861321] [NEW] ceilometer-collector fails to stop if cannot connect to message broker

[Liam Young]

Public bug reported:

ceilometer-collector fails to stop if it cannot connect to message
broker.

To reproduce (assuming amqp is running on localhost):
1) Comment out the 'oslo_messaging_rabbit' section from /etc/ceilometer/ceilometer.conf. This will trigger ceilometer-collector to look locally for a rabbit connection
2) Start ceilometer-collector 
3) Observe errors like below in /var/log/ceilometer/ceilometer-collector.log

2020-01-29 18:28:35.848 11808 ERROR oslo.messaging._drivers.impl_rabbit
[-] AMQP server on 127.0.0.1:5672 is unreachable: [Errno 111] Connection
refused. Trying again in 32 seconds.

4) Stop ceilometer-collector 
5) Check if ceilometer-collector processes have gone
