Update centos RabbitMQ to 3.5.4

[Matthew Mosesohn]

In Ubuntu we deploy RMQ 3.5.4, but 3.3.5 in CentOS. I am working to add SSL support for RabbitMQ on Fuel Master, but there are known security vulnerabilities with its SSL implementation in <3.4 versions. Furthermore, we should not have a version discrepancy between major components across CentOS and Ubuntu.

Actually, we use 3.5.5 in CentOS

This output from rabbitmq container (master on centos 7)
