The idea is to add another parameter to the function RPCCLient as:

RabbitMQ test with different libraries

I made a few tests with different client libraries.

Environment:

• Laptop 12 cores, 32 gb ram
• Two rabbitmq nodes in cluster ( same machine)
• RabbitMQ version 3.7.13 - Erlang 21.2.4
• 64 async threads for each server
• Ubuntu 18.04
