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

# Creates 400 vhosts
# Related to https://github.com/rabbitmq/rabbitmq-server/pull/1770 & https://groups.google.com/d/msg/rabbitmq-users/ZbTNp6YqZeo/53JLiy2zAQAJ
# Clean up with rabbitmqctl eval '[garbage_collect(P) || P <- processes()].'
# To see this behavior (for a longer time) in 3.7.9 you need to turn off background_gc_enbaled: {background_gc_enabled, false} in rabbitmq.config

for i in `seq 1 400`;
