Prepare a script for setting up a testing instances of RabbitMQ

[Manik2708]

Currently we are testing the functions related to Redis, Mongo, Cassandra and RabbitMQ by integration testing. We can easily create testing instances of most of the services except RabbitMQ as it doesn't allow to setup more than one instance on a single machine. We are using Docker Compose currently but it will make the future CI slower. We have to think of a new approach.
