Fix file_descriptors total_limit in rabbitmq_limits role

[chris]

Description
===========
Ansible role `rabbitmq_limits` Task `Get file_descriptors total_limit` has incorrect command line argument.

~~~
"{{ container_cli }}"
    exec $("{{ container_cli }}" ps -q --filter "name=rabbitmq" | head -1)
    rabbitmqctl eval 'sysctl -n fs.file-max'
~~~

Running `openstack tripleo validator run --validation rabbitmq-limits` fails with the below

"stderr": "Error (argument validation): \"syntax error before: fs\"\nArguments given:\n\teval sysctl -n fs.file-max\n\n\u001b[1mUsage\u001b[0m\n\nrabbitmqctl [--node <node>] [--longnames] [--quiet] eval <expression>\nError: non zero exit code: 64: OCI runtime error",

Running that command which fails in the ansible task
~~~
podman exec $(podman ps -q --filter \"name=rabbitmq\" | head -1) rabbitmqctl eval 'sysctl -n fs.file-max'
Error (argument validation): "syntax error before: fs"
Arguments given:
        eval sysctl -n fs.file-max

Usage

rabbitmqctl [--node <node>] [--longnames] [--quiet] eval <expression>
Error: non zero exit code: 64: OCI runtime error
~~~

Verifying the proposed solution works

[root@overcloud-controller-0 ~]# podman exec -it $(podman ps --filter name=rabbitmq-bundle -q) sysctl -n fs.file-max
