spring_rabbitmq_addresses environment variable is ignored

When trying to configure XD to use a RabbitMQ instance other than the default localhost:5672, a user is supposedto updated the "spring_rabbitmq_addresses" environment variable or the spring.rabbitmq.addresses setting in the servers.yml file. In this case XD is ignoring this environment variable.

Steps to reproduce

1. set the transport by using "export XD_TRANSPORT=rabbit"
2. set the spring_rabbitmq_addresses by "export spring_rabbitmq_addresses=foo:5672"
3. Startup a admin container on your local machine
4. deploy ticktock
   • this should fail
   • start up a local rabbitmq
   • deploy a new ticktock and stream will deploy.
