rabbitmq_user.present change perms every start

[Руслан Гизатулин]

Hi!

I use salt to setup rabbitmq cluster. Users created at first node only. After every apply formula there is change with  diff: 

Changes:
              ----------
              perms:
                  ----------
                  new:
                      ----------
                      testuser1:
                          ----------
                          configure:
                              .*
                          read:
                              .*
                          write:
                              .*
                  old:
                      ----------
                      .:
                          *

Permissions in formula look like - perms: [{ "testuser1": ['.*','.*','.*'] }]

Perhaps someone has already encountered such a problem? Or it is bug?

I don't use the salt formula. It used shell cmd at the time and not the rabbitmq module.
This is the relevant snippet we have in our for user management:
```yaml
# Apply Clusterwide config only on master node and standalone node.
{% if salt['pillar.get']('rabbitmq:master', undefined) is not defined %}
  # User management
  {% for user_name, user_conf in salt['pillar.get']('rabbitmq:user', {}).items()|sort() %}
rabbitmq_manage_user_{{ user_name }}:
    {%- if user_conf.present|default (true) == true %}
  rabbitmq_user.present:
    - name: {{ user_name }}
      {%- if user_conf.password is defined %}
    - password: {{ user_conf.password }}
      {%- endif %}
      {%- if user_conf.tags is defined %}
    - tags:
        {%- for tags in user_conf.tags %}
      - {{ tags }}
        {%- endfor %}
      {%- endif %}
      {%- if user_conf.permission is defined %}
    - perms:
        {%- for perm_vhost, perm_config in user_conf.permission.items()|sort() %}
      - '{{ perm_vhost }}':
          {%- for perm_value in perm_config if perm_config|length == 3 %}
        - '{{ perm_value }}'
          {%- endfor %}
        {%- endfor %}
      {%- endif %}
    {%- else %}
  rabbitmq_user.absent:
    - name: {{ user_name }}
    {%- endif %}
    - require:
      - service: rabbitmq-server

  {% endfor %}

{% endif %}
```
```yaml
# exemple
rabbitmq:
  user:
    guest:
      present: false # Disable a user, it's best to diable guest user, or at least change it's password.
    admin:
      password: "VeryHardPassword" # Password field is optional, but please set one !
      tags: # Tags list are optional, see https://www.rabbitmq.com/management.html#permissions for the list of tags
        - administrator
      permission:
        "/": # On wich vhost to apply the permission
          - '.*' # On wich queue can he configure
          - '.*' # On wich queue can he write
          - '.*' # On wich queue can he read
        "toto":
          - '^adm\.' # Only allow for queue who start with adm
          - '.*' # On wich queue can he write
          - '.*' # On wich queue can he read
    monitoring:
      tags:
        - monitoring
      present: true # This is useless since it's the default value, but you can set it.

```
Not sure if you are willing to do thing yourself ? if so this can help but isn't enough on it's own :)
